Last night I joined the Association for the Advancement of Computing in Education, specifically for the Social Media Seminar, which hosted a free (I believe monthly) event at around 8pm UK time (quite convenient), a really interesting discussion (again, particularly the ‘backchat’), which can be followed on Twitter at #smti. Once on the Ning site, I joined the Social Learning group, and got some more good links  for talking about in my Twitter session later today!
