Wikipedia is continuing to grow exponentially, both challenging and exciting us. I have just been reading about Barbie. If you haven't had a look, you should. An amazingly comprehensive overview of her development, evolutions and make-overs and her cultural impact. Did you know, for instance, that she has been both a palentologist and tourist in her time (as well as, of course, astronaut, vet, rock star and firefighter)??
There's a lot to be said for the power of wikis to enable collaborative work across space and place.
And a further note on Barbie - the amazing Simon Tyszko has Suicide Bomber Barbie depicted on his site - more evidence of the way this iconic doll is hijacked as a mechanism to critically reflect on key contemporary issues.
