Dawn Hogue has a great post on blocking access to Web sites.

When schools block web applications, especially the newer Web 2.0 tools, the opportunity to use and teach how to use these tools is blocked as well. What would be better than simply blocking everything would be to acknowledge that there are some risks associated with accessing information on the Internet and in creating an online presence and teach students how to be responsible Web content generators.

Amen!

I checked out her resources page and imagine it will take me some time to sift through all the great stuff.
