Serious Business is just what it sounds like. In SB you can post something you don't want people to fuck with, or a discussion that isn't allowed to degenerate into "no u". Extensive, intelligent discussion is carried out here.

SB has three rules:

1) Keep it topical. If it's not serious business, it doesn't belong in Serious Business. Use your heads, guys.

2) If a topic is very popularly discussed, a thread for it may already exist. If it's not weeks and weeks old, resurrect it rather than making a bunch of duplicate threads about the same shit.

3) DON'T BE AN ASSHOLE. This is not Gaia Online. We're all capable of not being complete douchebags here.
