I guess it was fairly predictable that, sooner rather than later, there'd be "blog controversy." Why not? Everything else appears to be "controversial" these days.
Just for the record: Although the HuffPo certainly features celebrity bloggers, there's a whole raft of us who aren't technically "celebrity" bloggers. I'm far from famous -- but Arianna did want to include some "local" bloggers and "policy wonks" who have ears to the ground about issues that are important. We're here too.
One of the great things about blogs is that you don't have to read anything you don't want to read. If you're one of those folks who doesn't care what celebrities are thinking, don't read what they're saying. Read the other stuff. It's in here.
