I was sent this today (Thanks Tamy!) which has renewed my enthusiasm for wikis (if not SL!)
http://sleducation.wikispaces.com/educationaluses It has convinced me that wikis can look good, so I’ve revisited wikispaces. As well as the basics you’d expect, you can restrict editing to named people, lock pages and use widgets to embed lots of social software stuff – a delicious feed, flickr slideshow, YouTube video etc.

I’m planning on using this, rather than just a del.icio.us list for a future workshop. The idea being that as well as the resources I’m providing / demonstrating it will be a workspace for a hands-on wiki exercise and possibly a resource that gets added to after the event but that might be expecting too much. The only downside I’ve come across so far is the Google ads although they are quite discreet.

I’m also wondering if there is a area of our website that it might suit… for demo purposes if nothing else.
