150 monkeys

I've heard this before, but it looks like this is where the concept started: a human can know about 150 people at the same time, which affects how small groups differ from larger ones. Although I've heard 30 people is about the point at which corporations need to start working on rules for interactions. From Gene Expression, from the Belmont Club's discussion of terror cell size, from Instapundit.
