This is a very simple question to a very complex problem/issue. Simple answer it isn't possible. The current way the internet, law, and society works it is impossible to start a anonymous blog. You can create hurdles and do simple things that would stop the easy to find things. But, if someone or corporation really put any effort into finding you they could.

The internet was not design for people to be anonymous. Our law's weren't made to keep you anonymous. Our society doesn't allow for people to be anonymous.
