2 years ago, I reviewed a site called Diigo which was still in beta. Basically, it merged the ideas of social bookmarking, like del.icio.us, and social clipping, like Clipmarks. Diigo allowed users to highlight text on websites, to annotate it, bookmark the page and then tag them.

Diigo v3 places more emphasis on the social aspect of social bookmarking through merging ideas from several different sites together. For example, it takes annotating from Clipmarks, bookmarking from del.icio.us and a facility which suggests websites you may like based on your annotations from StumbleUpon.

Diigo v3 has some unique features which I like. When you are on websites, you can view what other users have highlighted and annotated which is useful for group projects where collaboration is necessary. You can also join groups and communities and send private messages to other users. Another interesting feature is WebSlides which lets you view your bookmarks as a slideshow which is useful if you can’t always remember the name of the site but you can remember the way it looks!

You can obviously tag pages and friend other users, like you can on most sites!

Diigo 3, much like it did 2 years ago, uses a toolbar in Firefox, Flock or IE or a bookmarklet in other browsers.

So, some key points about Diigo 3:

1. Easy to share annotations on certain websites; useful for collaboration
2. Improved social features
3. WebSlide browse through websites based on screenshots.
4. Clipmarks is like cutting something out of a paper; Diigo is highlighting something out of one and annotating it!

I believe Diigo is probably more useful as a research tool than as a social site but it is nice to merge the two together!
