A cellular theory of communities
[Communities grow less like linear software products and more like multi-cellular organisms. If the conditions aren't conducive, the entire structure can collapse.]
[It's easier for cells to stay alive when they are smaller. Multi-cellular organisms grow by producing more cells.]
[Might be more strategic to build a large community by connecting many smaller, more intimate micro-communities. Enlarging small groups destroys the qualities that make it potent.]
To scale a community, build lots of special, one-of-a-kind places for a few people at a time, and then work with the most active members to build fast interconnects between them.
