Hot Air got deleted from my daily reading link stack a couple of weeks ago. I get nothing out of it, anymore. Whether it's Ed taking on the air of someone that's not part of the establishment, to hiring out more of the writing duties to interns, I don't know. I do know they've lost their mojo, for whatever reasons.
Rocketman/KarlMagnus/Sockpuppetboy still hangs out there, though. That more than anything, speaks to their remaining audience.
