Social search has a brand new contender - Diigo Currently social search appears to be the hottest topic on the internet. The theory is that more useful and meaningful search results can be gathered regarding the true value of sites by getting users to recommend websites rather than utilising a series of computer generated algorithms.Traditional search engine results, such as those supplied by Google and Yahoo!, are primarily based on objective criteria such as counts of the backlinks from other sites. These links are seen as votes on the importance of that page for a given set of criteria. Social search allows users to assign their own votes regarding which sites are worthwhile, by sharing bookmarks of favourite sites, adding their own subject tagging, or making annotations to listings. This creates a more subjective set of results, which some feel can more accurately reflect which sites are most meaningful for particular search terms. The concept of social search has been continually evolving since social bookmark sites like Del.icio.us and Shadows first appeared through to more involved services such the social networking sites MySpace and MyWeb, or the social news source Digg.Now a new player has appeared on the scene. Diigo (Digest of Internet Information, Groups and Other stuff) which was launched on Monday aims to combine a number of features such as shared bookmarking, blogging and web page tagging into a single service along with a powerful toolbar search tool.Diigo promotes itself as an online social research and "social annotation" tool, allowing users to:"Collect, share and interact on online information from anywhere”. By letting users quickly create their own comment on sites as well as highlight, clip or make sticky-notes for webpages, and providing access to organic search or their own social search results, which can be adjusted to suite the users preferences, Diigo has created a service with several interesting resource sharing and community promotion features. By taking onboard search features normally associated with search toolbar extension filters such as the ability to restrict keyword searches to the site you're currently viewing, the usability of the search functions have been increased to make this a useful service regardless of whether the user is looking to fully immerse themselves in the online social environment.While there is currently no direct official link between social search results and organic results obtained on the traditional search engines, many users have recently started to find information from the likes of MySpace creeping in. With Google and Yahoo! both having their own networks it looks likely that more of the features and results will either be merged together or be offered alongside each other so that you can get different sets of results depending on your preferred search method.Whether Diigo is here to stay or is set to quickly disappear like many other social search sites, remains to be seen, however the simple customisable interface and powerful set of useful tools make this one of the best offerings for some time.

But Diigo! Diigo lets you annotate webpages, among other things. You create an account (all of these accounts are free), and then while you’re viesing a web page, you can highlight a bunch of text and, in effect, leave a permanent sticky note on that site, so whenever you view it, you can view your annotation. You can also make these annotations public to other diigo users. I have wanted a tool like this for at least five years. This changes everything.

SOURCING TIP: And Diigo was its name-O One thing I have been ranting about (online and offline) is the need for a tool that will allow researchers to seemlessly share their intelligence. Imagine (as I often have) the time that would be saved if I were to discover a resume online and then see a note left by one of my co-workers that reads, "Been here, done that and submitted the candidate." Wowzers! That would really cut-down on duplication of efforts wouldn't it?

Okay, so let me show you something  I really like and am recommending that research teams use - Diigo. This FREE product has enough features that I would willingly pay for it and from me, that is a high compliment. Here are a few highlights from the VERY LONG list of features they offer. (Man, these guy are good!) A few highlights from their website... The Best Web Annotation Service: Add highlights and sticky notes on any web page, anywhere, and access them anywhere. A Great Webpage Clipping Tool: Highlighted portions of any webpage are clipped and collected centrally, which can be shared and searched. An All-in-One Bookmarking Tool: Bookmark webpages to Diigo, local folder, del.icio.us , Simpy, Furl, Spurl... and make them permanently cached and full-text searchable. A Great Collaborative Platform: Share and interact on online findings, complete with highlights and sticky notes. The Most Customizable Search Tool: Like Google's toolbar, but far more customizable, so you can access any search service with one-click --- music, maps, references, local library, New York Times, ... Unique Content Selection Menu: Interact with any word on a webpage just by selecting it, no click needed! - highlight, search, look up - whatever you you want!

With a virtual highlighter and digital sticky notes, now you can highlight & jot down your comments directly on any part of a webpage and scan through all your research findings quickly. Keep your annotations private or share with others. Exchange viewpoints on any specific area of a webpage - great for collaboration or debating an issue. Tags and full-text search on everything make it extremely easy to organize and find stuff - no need to fumble with folders and subfolders. You control the privacy setting on what can be seen by public or kept private. Need someone to pay special attention to a particular section of a webpage? You can forward a webpage with your highlights & Sticky notes. For further interactions, your friends can append their comments under your notes right on the page.Discover relevant / new content based on specific users, topics of interest, recommendations, hot lists, and more. For example, to discover high quality contents on some subject, check out bookmarks under specific tags - remember these represent the joint effort of lots of people.   ** Now here is something that I think is a killer feature! I download the Diigo toolbar and when I come to a page that has been annotated, I am notified (see arrow). I can set this to show me only the notes I have left behind or, the public notes of others. And get this, once I set up my free web-based account, I share that info (my log-in) with my co-workers and all of the annotations we mark private are only seen by us. (Wink) Ahhh... now this is a tool worth noting, using and (above all else) sharing with other researchers on your team. (Click here for virtual tour of their product.) 4-Star recommendation!!!
