demablogger
A portmanteau of demagogue and blogger, it is a person who uses a blog as a soapbox from which to preach to the unwashed masses and the rest of the world.
Compare to pedablogger, who uses their blog to educate rather than to orate.

Pete with his 'rant of the day' is one of the most entertaining demabloggers I know.
