Blogs in education are endagered. Why? Read what Weblogg-ed has to say about it. Then get ahold of your representatives in Congress and tell them how you feel.
Yes, I know they're mainly targeting MySpace. Unfortunately, the bill is so broadly written that most if not all blogs will have to be banned at school.
I'll have more to say about this later, when I've had time to collect my thoughts.
EDIT: A wiki has been set up to create a collaborative letter to our congresspeople. I've already added my (minor) contributions and sent one to my Representative. A link is included near the top to allow you to contact your Representative quickly and easily.
