I've been mulling an idea for awhile on creating a place where people can go to get all their Web 2.0/21st Century Tools information.
Also, I wanted something that would be of a collaborative nature where other people can post/review sites.
Finally, after sometime I think I created a nice little place for such a thing in a wiki format. This site is for everyone who likes to use innovative technology and apply it to their teachings.
Feel free to join the wiki and use/share it anyway you see fit.
