Keep it to temptation! I personally wouldn't want Fark or Goonsquad playing BM. I play another game with those two communities involved (and once upon a time even 4chan or /b/ played) and.. well, I'm not sure they'd fit into the niche of BM.
I'm glad you knew what I was thinking about. I know some people from those groups would love to play BM and even RP quite well (I met a few really good guys for international rping on /tg/) but depending on where you advertised you might get lots of interest from the wrong places. At the very least the titans would have their work cut out for them.
