One thing that isn’t obvious (yet) on Quizify is how to share a quiz. I corrected a broken link posted by Amir Dekel on Twitter, and I’m reposting here for everyone’s benefit.
Linking to a quiz is very simple, http://quizify.com/edit?url= followed by the URL of the input file. There is no way yet to link to a quiz created via manual input, but that will come eventually.
First post on the Quizify blog! (Okay, second, since I write a single post when I attempted to get Quizify started a couple of years ago).
Anyhow, this blog will keep you posted of news and updated for Quizify. And later on, I’ll update the design to match Quizify proper.
Happy Quizifying 
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.
