I’ll start.
I nominate mattdenn.blogspot.com. Denn is a very funny natural writer. Although he is no doubt smart enough to “filter” on the fly, you still get the feeling that his blog strikes fear into his campaign staff. (See the current post for example. oh what I could do with that if I had no soul and decided to work for the dark side.)
The only thing I don’t like about Denn’s blog is not being able to comment. Whenever I try I get a message that says, “Comments on this blog are restricted to team members.” And I guess I’m just too lazy to figure out how to become a team member.
