There is a prevalent "Hockeyer-than-Thou" attitude among some of the posters, who seem to think they are always right, and therefore, those who disagree are lesser. These posters have a tendency to make fun of people who make comments that they disagree with, and to continue to do so long after the thread should have died down.
Look, if I could take F&B, G.O.D., and BP down, I would, but I can't.
I voted (again) for Japers' Rink and Peerless.
I comment and read Japers' Rink several times a day, because as far as Caps news is concerned, there's nothing faster updated.
As far as the content asked for, Japers' used to do a far better job of "Telling both sides", but it's kind of drawing back. Right now, it seems if the bloggers have an opinion, everyone else (Mostly comment posters, and you'll very rarely see two of the bloggers disagree)kind of agrees, and disagreement isn't too common. Sometimes you'll post disagreement, and get kind of jumped on, but I'd rather have that than everyone agreeing (Which is what tends to happen over at OFB).
More to the subject, J.P. himself used to have a "Why the (other team) will win" segment, and I always thought that was neat. There were a lot of things that didn't survive the jump from .blogspot to SBNation, and I still don't know how I feel about the move (I guess it was for the better).
More on the idea of SBNation, there's no better way to get the other side. The Writers don't really need to tell the other side, because someone else can post a fan shot or a fan post, and if you want to know about the opponent, you can click their link in a game day post.
Irockthered nailed it when she said Japers' Rink was the most "comprehensive" Capitals site. The rest are good reads and for making you think, but there's far more content for your entertainment dollar at JR.
