Me 'three' (as in I agree with you Karen and Shaun) the Wiki environment would be great for hosting rich media content and Web 2.0 tools. I like the idea of challenges, particularly if there could be some student involvement to encourage teachers to use the tools authentically and with purpose in their classes and schools.
Many thanks for all your comments. Apologies from me - now I realise the actual 'poll' wasn't live so well done all of you for just jumping into the thread instead. Flexible and adaptable folk, all of you.
I'll set up the shared page today and we can get cracking!
