Teaching Hacks a blog dedicated to outlining . . .well hacks for teaching . . .ergo the name, has just added a wiki to the site. Right now there is not much content there, but this then is sort of the point I guess. Wiki’s are supposed to be collaborative efforts. Teaching Hacks has in the past been more focused on K-12, but this site looks like it could develop into an excellent resource for all levels. Quentin D’Souza, the author of this blog/site, also has one of the better rundowns on using RSS for educational purposes, which you can now get on the wiki.
