I actually went to a bodybuilding.com forum meetup/training session two days ago. Pulled a 120Kg deadlift, a personal best for me, and as they say at the Misc "feelsgoodman.jpg". Everyone was really cool.
I'd say probably 85 per cent of my posts on bb.com are in the misc. It brings all the lulz I can possibly need in a day (The Australian theme meme thread was especially amazing) and in between all the silly threads and trolling there's actually good discussion there too.
