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.

Annotation is Suddenly Fun Each semester, I try (in vain, usually) to get my students to annotate their text book. I do this to prepare them not only for future studies, but also for the annotation that research demands they do. Diigo, suddenly, makes the students want to annotate their bookmarks. It is their chance to make sure the world (or their group) knows how important specific words on a webpage are to them.

Diigo is fantastic social bookmarking and proto-blogging tool, marrying the best of del.icio.us, the leading bookmarking site, and Google Notebook, a recently upgraded and highly flexible tool for interacting with and reviewing your websurfing experience. I didn't spend much time with Google Notebook once I discovered it by way of comparing del.icio.us with Google Bookmarks, but I played with it enough to notice a lot of excellent features that del.icio.us did not have, including the ability to automatically associate bookmarks with a current project, flexible blog-like layout for groups of bookmarks, and collaboration features. As I moved bookmarks into Google Notebook, I started to realize I would be missing out on some advantages of del.icio.us, such as strong interconnectivity through tagging and an exceedingly simple and crisp interface. Enter Diigo, which retains del.icio.us's advantages while sprucing it up with notetaking, tagging flexibility, and collaborative features that rival Google Notebook and then some. I compare these three approaches to bookmarking on four fronts: tagging, blogging, collaboration, and "other stuff".

Tagging: When I'm surfing, I almost never want to slow down to tag or detail the links I'm saving. I'm either just browsing, and I just want the page to be saved in some repository of "cool" somewhere I might be able to check it out later, OR I want to save the page and others to come back to for some project I'm working on. Although its actual tagging features (labelling) are limited, Google Reader was cool because it would automatically save links to the notebook I was currently working on, which seemed easier than having to tag the page every time I save for del.icio.us. Diigo isn't quite this easy, but it does provide the option of setting default tags so I can cruise through surfing without pause. It also allows you to change tags for multiple bookmarks at once, a feature that has been delayed in del.icio.us during the extended wait for version 2.0. Winner: Diigo

Blogging: Sometimes, I don't want to put a whole lot of thought into consolidating my links into one coherent group. In this regard, all three services provide suitable options for tossing together semi-coherent groups of links on independent webpages for others to see. Google Reader does a good job of making scraps from around the internet look palatable; see this example about ultralight backpacking gear, but it does not offer the same level of interconnectivity that del.icio.us or Diigo provide. A similar example from del.icio.us shows it's limitations: the links cannot be groups under one note or be put into any order other than alphabetical or chronological, and pictures and other non-bookmark material cannot be added. Diigo does not have any of these limitations: its lists can be ordered as you please and divided into sections, and they are built independently of the tags, so you can draw bookmarks from anywhere into the page, as you can see in this example. The option that makes Diigo stand out is its ability to transcend the status of "proto-blog" by easily exporting links to the blog of the user's choice. By simply selecting links and clicking "Send to Blog >>", a skeletal blog entry is started in Diigo which can be fleshed out and published on the spot. Winner: Diigo

Diigo, "Digest of Internet Information, Groups and Other stuff", the web2.0 social bookmarks and annotation service, has finally announced going public today!*I've been waiting for this to write about it, well here it goes:Diigo is a great, no, a fantastic tool(!) Not only for bookmarking but also for research, blogging and a must for any social bookmark mania. It's a kind if mix between del.icio.us (social bookmarks), Wizlite (web highlight and notes), Onlywire (multi post to social bookmarks), with Blogging support. Diigo vs Flock: In fact, there are some similarities with Flock, the web 2.0 browser, though you can install Diigo on Flock you'll get some close features, like: blogging: They both support WordPress, Blogger, LiveJournal, Typepad and MovableType for now (+Dupral for Flock) exempt that Diigo, instead of a blog editor, uses the online blog editor.+ In flock you can save your post for later, in Diigo you can clip the text you want and blog from your bookmarks later on. (See an example, select all and expand to see what I mean.) Bookmarking: Both have a one click bookmark. Flock can sync and bookmark to Shadows and deli.cio.us. Diigo's, called QuickD, let's you set a custom tag and also can simultaneous bookmark to: de.licio.us, BlinkList, Furl, Netvouz, RawSugar, Simpy, Spurl, Yahoo, locally... and of course at Diigo! Search: They both have good search but very different. Flock can search though bookmarks, history, the web and add search plugins like in Firefox. Else Diigo let's you completely customize, add search engines and display them in one or more dropdown menus on the toolbar. (For example, I customized a part of mine for searching though social bookmarks: digg, del.icio.us popular, Netvouz, Hatena...and the same menu that will search my bookmarks.) And at the Diigo website there's an in-page pop-up advanced search which let's you search tags, url, title, phrase, in comments, in highlight or anywhere for only user's or community bookmarks.So using both, Diigo AND Flock, makes you someone very very... social!? ;-)Highlighting:This is the main interesting feature in Diigo.You may not have the Flock's RSS reader support*, nor the drag and drop Flickr or PhotoBucket toolbars but you can Clip text and images, Highlight, Web notes and Aggregate the clippings. Aggregating clippings lets you collect text on the web and later view them all on one page, very useful for research and blogging. See the screenshot. Diigo's highlighting styles Other special features: A bookmark status icon on the toolbar shows if the page has been bookmarked by you, has been commented by any Diigo user or both.Tag cloud which is also a batch tag manager. [Screenshot]Batch selected: Set the selected bookmarks to public/private, mark as read/un-read, expand details or delete them. Quick access: A customizable drop down menu to quickly access any bookmarks of a certain tag. Forward: Email link AND clipping. (usually it's just the link.)Highlight: Search terms like the Google toolbar but also possible on bookmarks and inside non expanded clippings.Tagging: They can be comma OR space separated!Delete: This is a small detail and would be better shown in a video but I love it: When you delete a bookmark it 'flies out' and disappears with a zooming effect! ...and of course it's a one click delete. + all the usual features, and not so usual features like: import directly from browser bookmarks and del.icio.us, follow a tag, user or search results, RSS links, Unicode support, an Ajax linkroll generator and much more... This without mentioning what's comming up! (API included!)As you see, they have done many updates since they started in Decamber. If you want to see more there's a recent review by John from Libraryclips and very good and complete help pages with screen-shots at Diigo.Note: The toolbar exists for Firefox, Internet Explorer and Flock, but incase you find yourself in an internet cafe, there's also an in-page bookmarklet for bookmarking. All the rest, annotation, blogging... comes with it's the toolbar.I've used, and still use now, the Diigo toolbar along many other extensions, where in the beginning it did have some compability problems, it's been a while I haven't had any.*I want to apologise to all the diigo team for the other day with a special thanks to Maggie Tsai for her kind understanding and reaction. -Some of you may know what it is, if you don't I won't tell you.
