I kept hearing about it on other mma-sites, always referenced with fearful, bated breath.
An mma-journalist at mma-fighting who's podcasts i used to listen to back in the day, always went out of his way to diss Sherdog forums, like it was full of gangsters, punks, pirates and lunatics. That, + the good folks at bloody elbow that always talked about how Sherdog was just the dregs of society, literally 'the worst'. Bloody elbow being what it is (or was, haven't read it in years) i figured Sherdog could very well be the best. Turns out it was (is). Have been lurking for 5+ years before becoming a member recently.
I still prefer to read mma-articles and news elsewhere, but the heavies here is the best place for open, non-pc mma discussion.
