More on Web 2.0

Classroom 2.0:

Social networking for teachers interested in using Web 2.0 technologies in their classrooms.

Ning:

Make your own social networking group, allows for a "private" option making it useful for creating a community around the students (and possibly their families).  Blogs for each user, photos, discussion forums, and events calendar.  Pretty cool.

Writeboard:

Allows for collaboration on one word document, password protected.  Great for shared writing projects.

Jottit:

Really, really, really easy way to create a quick website.  Definitely helpful if you're crunched for time.

CommunityWalk:

Add photos, notes, videos, and more to a map.  Good for documenting local history projects, field trips, walking tours...
