Thanks to TechCrunch I found The Best Web 2.0 Applications For Education — 2007, which lists mostly things that aren’t necessarily related to education. But there were a few gems in the list. CLEAR has a number of tools for language teachers to create web-based learning tools. ESLvideo.com is neat, as just like Quizify it takes advantage of existing content on the web.
Also via Facebook I found ExamsRUS which seems to be trying to do a lot of things that are themselves not new but rarely done all at once: course ratings, course info, professor ratings, course materials sharing, etc. It’s also done out of students/alumni(?) of my school, so I will have to see if I can take advantage of that situation.
