I disagree with your "Clinton love fest" assessment of MyDD. I was an Edwards supporter who is leaning Obama, but I couldn't take the hatred being spewed at Kos. And the poster above is right, the Obama darkening claims that Kos front-paged was the jumping the shark moment for me. That he hasn't had the class to apologize for those accusations just affirmed that I had made the right choice.
I see a fair amount of pro-Obama diaries here, though there is no doubt there appears to be more Clinton supporters. However, the invective here is considerably less than at Kos on both side. There are notable exceptions: I've seen overt racists here trashing Obama, and I've seen some of the same, non-thinking juvenile attacks on Clinton that dominate at Kos. But for the most part, it's been a far better place to visit.
