I'd say the board is more about pro bodybuilding now than ever. The Mr.Olympia thread was packed, but how often does the IFBB hold shows that feature the top guys?
It's the same every year - traffic and activity peak during the month around the Arnold Classic and Olympia, with most threads being bodybuilding-oriented, and then settles down to the current level, with a lot more offtopic threads. It used to be very busy year-round until late 2006, but a lot of industry people and good posters were active back then, unlike today.
There's only so much you can discuss about bodybuilding anyway. Which is why most of the vets here pace themselves and post about other things than just men in thongs all the time.
