Well, it isn't exactly surprising, but (with apologies to Eric, who runs a great blog) this was my favorite baseball site ever. I'm sure it got way bigger than they guys who ran it could've possibly dreamed of.
What was great about it was that those of us who think intelligently about baseball (and get shit for it from dumbass sports journalists) finally had a way to strike back and strike back with vicious humor. Some journalists reacted by cleaning their acts up (remember HatGuy?), and some reacted with hostility (that prick Jon Heyman). A few of the better journalists (Jeff Passan) mentioned the site with approval. I'm sure the more prominent sabermetricians just sat back and smiled.
It got to the point where (I swear) Joe Morgan actually cleaned his act up a bit this year. Someone must've told him that he was becoming a huge joke among younger baseball fans, or something. You could see it in the JoeChats which were nothing but FJM fans baiting Joe.
So three cheers for what these guys accomplished. They will be missed.
