While completing the last task in Module 4 Searching the Web, I came across this an amazing web app Diigo.
Essentially it's a cross between social bookmarking and a research/reference tool where as you can not only bookmark a site, but highlight words or leave a sticky note with annotations ON THE PAGE for future reference. Diigo bills itself as a research tool and knowledge sharing community. While I haven't had a full play with it yet it's free to set up an account so hopefully tomorrow I shall be able to poke around and see how it works.
The ingenuity of people on the web never ceases to amaze me!
