Diigo

I have recently had a look at Diigo which is defined as a "Personal information management system". It is essentially a social bookmarking site which allows one to share a library of accumulated bookmarks with communities of interested people. This sharing is facilitated by bookmarking features which allow target items to be appropriately tagged, annotated, and shared with groups a user may be apart of. The Diigo toolbar allows information to be quickly imported from the web and inserted and organized into a personal/group library. Fragments of sites can also be highlighted, screen shots taken and then archived for future reference if necessary.

I have managed to put together a small library of interesting content from a number of resources. Although I have not managed to use it as a social tool as such. I can sea the sites potential as a research tool for people to get together to accumulate and share information from which a knowledge tree can be constructed. I can see the value of using the wisdom of crowds to aggregate and organize useful content from the web on a particular topic. This site could be useful for students or small research groups.
