Like Jason, I was impressed by Clay Shirky's analysis of the LiveJournal community. Especially his findings about groups of 12 and how they allow people to have a satisfying experience. Since then, I've been noticing groups of twelve. Maybe it's a natural way to organize. I tried to come up with a list of famous 12's.

Now the question is, how do you build community software that accommodates groups of 12, and encourages that equilibrium point? And how can the whole community scale (another great article on the subject by Clay Shirky) without loosing their individual group identities?

Are there other famous 12s?

- 12 apostles in Christianity
- 12 causes of samsara in Buddhism
- 12 tribes of Israel in Judaism
- 12 people on a jury
- 12 months in a year
- 12 signs in the zodiac
- 12 original American colonies (ok, 13 if you count Delaware)
- 12 days of Christmas
- 12 tone musical scale
- 12-sided snow crystal
- 12 immortals in Greek Mythology
- 12 beers in a 12-pack
