What do I think about Blogging? I'm not so sure about it yet. I guess it's a fun way of letting your classmates and teacher know things about you. It's a lot like the whole Myspace thing which got old to me very quick.
I don't see where blogging for K-12 could help or hurt anything. The bad thing about it is that people can get on and say whatever they want, good or bad. A good thing is that it could help students gain more knowledge about computers in school at a younger age.
