It reminded me of the the review tools in Microsoft Word which I've used a few times with students - someone sends me a Word document and I add comments and suggested edits. The review tools can track changes I make as well as highlighting sections and adding notes in the margin. I can then send the annotated Word document back to the author and a conversation grows around the original document and our comments. When I first started using this feature of Word, I thought it would be great if you could do that with web pages. Imagine being able to get a class of students to collaborate on a web page: to highlighting sections, share their understanding, ask questions and add extra information. With diigo, that's exactly what you could do.Add to that online social bookmarking (which can be linked to other bookmarking services such as del.icio.us), the ability to highlight any text on a page and search for it on a range of search services using a pop-up menu, to blog about a page and link non-diigo users to your annotations on that page (this blog posted was created using the diigo Blog this tool) and a host of other features ...and you have a stunningly valuable educational tool.

I have also found Diigo to be quite an exciting tool and this year my year group is in a better position to use it. I structured it into an independent activity during a literacy hour with my Year 5 children. Using Diigo I annotated a set of written instructions with comprehension style questions and the children answered them in their jotters. The children were accessing the site using a class set of laptops. I wanted them to respond someway online but took a simpler step to begin with to test the concept. It worked very well and the children were well motivated and on task - they managed well with the new tool and took it in their stride.

Social Annotation I have just read about a company currently in private beta called Diigo, which is in the business of social annotation (SA). Apparently SA is a superset of social bookmarking or tagging, which is of course the piece de resistance of ‘Web 2.0′. The question is can SA be an even better route to getting aquired by MAGY? Don’t quite me on ‘MAGY’ though since I am not sure what order those names should go in… I had been thinking about SA for some time but did not have the time / resources to get anything together for public showing - but this might be a good reason to do so. Of course given my record with getting code up on my blog I won’t have a sample till next year this time. Anyhow, the possiblities for SA are much more attractive than social bookmarking in my mind. With social annotations (at least what I consider it to be) I can surf to any web page and place tagged sticky notes (private or public) in a browser agnostic fashion that will contain my comments and refer to a certain block in the web page DOM. Then I can go to some central place to view / oranize my comments and can also subscribe to RSS of other people’s comments on those pages or from particular people.

The main problem that I have with Diigo (from the looks of their Flash demo) is that I need to install their toolbar - yuck!

The useful part of these systems for end users is that they can tag particular bits of content on a page and find exactly what they were referring to with a tag. Then if you combine this idea with microformats and the Semantic Web you might really be cooking with something combustible like methane.

Diigo: sharing and publishing bookmarks with tags and little comments attached to them is nice, but providing detailed annotations directly onto Web pages is even nicer, and Diigo is definitely leading the pack there. Annotations used to require the use of a dedicated plugin with initial releases of the application, but the company listened to persistent requests from users (including myself), and developed a plugin-free version as well. Definitely worth checking if you consider your bookmarking tool as a real productivity application.

8. Ramon deSilva  |  January 16th, 2007 at 3:20 pm Ismael, That was an interesting writeup. You covered a number of sites, and offered useful capsule summaries. I’ve looked over many of the sites you mention, and used del.icio.us, ma.gnolia, and Diigo. They are all good sites for bookmarking. But I think you overlooked a few points about Diigo that make it different from, and far superior to, any of the other sites. 1. As well as the ability to highlight and add sticky notes to web pages, you can collect the annotations from any set of pages (say, those tagged web-2.0-services) into a single source, with original URLs noted, to simplify your research. 2: The Diigo toolbar allows you to place all the search tools you might want, grouped by purpose, in a single button, so you can easily use multiple search tools for extensive research. The integration of this with bookmarking and annotation capabilities makes Diigo the most full-featured, capable research tool available. Diigo has other abilities; too many to list here. Overall, Diigo will save anyone who spends much time doing research on the Internet time and effort. True, you need to spend a bit of time learning all the features so you can incorporate them into your work habits, but the effort will pay off many times over. Overall, Diigo is the one service I find I cannot live without. There are other tools out there that do a nice job of this or that, and I use some of them. But Diigo is the only one I depend on throughout the day and could not live without.

How many users would like a del.icio.us++ where they can not only bookmark the URL, but also highlight specific parts of the page? Personally, I can’t live without highlighting: it helps me re-read the page, or realize that I’ve seen it before. -Laurent

(I-Newswire) - OFFICE 2.0, SAN FRANCISCO-- Sept. 6, 2007 – Diigo, www.diigo.com, is previewing WebSlidesSM, a browser-based player that displays any list of URLs complete with integrated annotations, sticky notes, and highlights as an interactive slideshow.  Diigo is also demonstrating WebSlides during the official Demo tracks during Office 2.0 conference.  More information on the demonstration schedule here: http://www.o2con.com/docs/DOC-1017. Diigo's patent-pending WebSlides, available at http://slides.diigo.com, enables a new way to easily create and share unique presentations based on web content and user annotations. To experience WebSlides, users simply collect and organize any set of links into a list, and add background music or voice narration.  By clicking "Play," the list transforms into a slideshow bringing Web pages and user comments to life. The player can then be sent to friends and colleagues and also posted on Websites and blogs. Viewers of the slideshow can interact on the slides through highlights and sticky notes directly on each page, without installing any software. This incredibly easy-to-use web-based software has many potential applications such as: - Create a guided tour for any website- Show a list of houses to real estate clients- Review a list of job candidates found online- Bundle important course resources for students- Provide a quick briefing, or a simple tutorial or guided tour on any subject- Share the favorite places you would like to visit with your friends and blog readers Diigo is a powerful, yet incredibly simple to use research tool that allows people to annotate, bookmark, highlight, save, and clip Web content that matters to them, for future reference or to share with others. They can also comment and add sticky notes directly on each web page, which are viewable by other Diigo users when visiting the same pages. About DiigoDiigo provides a suite of online research and collaborative research tool for individuals and small to medium-sized work groups. Diigo enables seamless bookmarking, tagging, highlighting, clipping, sharing, annotating, and searching of information to deliver a new level of productivity for knowledge workers. Diigo Groups also offer a simple and cost-effective platform for collaborative research. Upcoming releases will transform Diigo's powerful social bookmarking, social annotation and social networking suite into the next-generation knowledge management platform for large enterprises, through both hosted and appliance-based solutions. Diigo is privately held, and is based in Reno, NV.

Diigo has released v 3.0 of its browser plugin and has set a new standard in social bookmarking in the process. It not only allows you to bookmark and save notes in an easy to retrieve place, it adds a new dimension to the Web itself by revealing, at the page level, the community of people who have also interacted with the content. It also feeds into a bigger community of content that builds a social network around relevant information. It combines research and community.

Starting simple: You can bookmark and annotate relevant things that you need to reference later. Using the Webslides function, you also can share these links as a slideshow, which actually appear as “live” web pages. The slideshow is embeddable on Web pages and in blogs. Revealing a new layer of the web: The new sidebar gives you quick access to your bookmarks as well your annotations on each Web page. It also shows you other diigo users who have annotated that page to give you additional perspective. The sidebar is searchable to find your notes quicker and easier. Connect and Engage: According to the company, you are what you annotate. Bookmarks, tags, and annotations are one of the best representations of your interests and expertise. At Diigo, you maintain a bookmarks page which is your hub to relevant content. You can also connect to like-minded people and also browse their activities as they relate to you.

In the fall, I ran across a new social bookmarking site–Diigo. I started using Diigo with a paper that I was writing and loved it for several reasons. First, it’s a social bookmarking site which meant that I could peruse the links of other people on the site. Second, Diigo gave me the Furl functionality of highlighting and annotating, but the format seemed easier and the interface was more aesthetically speaking (in my opinion).  While I was in this stage of tinkering, I met with one of my dissertation committee members and I was talking about the focus of my dissertation–blogging. He very bluntly reminded me that my entire dissertation could not focus only on blogging, but needed to be focused on more features. I was in a bind–I wanted to focus on the advantages to writing that came from blogs, not all medias. But the more I played around with Diigo, the more a little grain of an idea began to grow. My dissertation should note about the advantages to writing–but about collaboration through Web 2.0

So, this semester, I went out on a limb and offered my students the option of collaborating on their research this semester. They were already not looking forward to the research, but the idea of using each other to further their research sounded like a good idea. Still, they weren’t jumping at the idea. Then, I gave them a quick walkthrough of Diigo. Their eyes lit up like they had just been given a present–and it wasn’t even their birthday. One student looked dumbfounded and asked: “Is it really that easy?” “It sure is.” I replied.

Students Use Social Bookmarking Just like I learned with blogging in the classroom, I know that students get more out of methods of learning that they use in their free time. So, social bookmarking was a way for me to engage my students not only in the research, but in conversations with the research. Social bookmarking, regardless of the site used, creates a conversation among members interested in the same tag. Each time a member marks a bookmark, they are speaking to their networks and saying “Read this.”

In my early days of Living in the Clouds, I was using Delicious as my cloud based bookmarking tool. It was my favorite Web 2.0 era tool. I loved it so much that I refused to look at any other social bookmarking apps. When I started blogging here at Cloud Avenue, Zoli recommended us to use another bookmarking site called Diigo for our research purposes. I agreed to use this app very reluctantly and I never looked back since then. Diigo is not just a social bookmarking site but it is also a very good research tool including options to highlight, annotate, comment, share, etc.. This tool has changed the way I do research on the web with its powerful set of features. In fact, I have stopped using Delicious completely. This is much more powerful than Delicious in my quest to organize my information in the clouds.

Pros: Highlight and Annotation. This is a powerful feature for anyone who is using Diigo for research purposes. The best part of this is the finer privacy control for annotation. One can keep it private or share with a group or make it public. Ability to create groups to share with others interested in a particular area or lists to organize information better for yourself. Ability to send to friends who are not members of Diigo through email. Ability to expand/collapse highlights and annotations in your Diigo bookmarks page. Powerful toolbar Ability to extract all the annotation in a particular page. Comes handy while researching on any topic. Here, the network effects can make this feature more powerful.

Cons: Lack of browser button that could hide/unhide the Diigo toolbar similar to Stumbleupon toolbar. This will come handy for those with smaller monitors/netbooks to use the space occupied by the toolbar to see the webpage.
