There are people, and companies out there that don't like bloggers. They don't like what bloggers have to say especially about issues dealing with copyright "gray areas."
If you are a blogger, and are concerned with your rights as a blogger and/or a journalist, then you should check out the bloggers rights page over at EFF.
Some of these are outlined on their bloggers main page. Here are some of them quoted directly from EFF:
Bloggers can be journalists (and journalists can be bloggers)
Bloggers are entitled to free speech
Bloggers have the right to political speech
Bloggers have the right to stay anonymous
Bloggers have freedom from liability for hosting speech the same way other web hosts do
That is all I am going to say about that right now...
