I saw this today - a kind of Facebook for grown ups and professionals with cool applications (you know, not Vampire bites or cute bunny hugs) like Huddle workspace so you can share documents and work on projects together. Here's the Huddle video:
I think this might be something I try out with my team. We are attempting to set up a cross faculty network of "talent" we can draw on to develop learning programmes for clients. I have started to set up a Ning community, but it has limitations. With this I could envisage everyone having a Linked In profile detailing their CVs, and using something like Huddle to collaborate on tenders and programme design....hmmm!! Sounds promising!!
