I know there’s a lot of social networking tools out there, but looking purely at the educational possibilities, I quite like the look of Infodit. Intodit allows you to establish a group site with a combination of wiki and forum functionality. It does this without undue complication and I can see it being a great way of focusing attention on an educational topic or project. By the way, I joined the Coldplay fan group!
