Communities, especially online ones, can live or die due to the behavior of members. Tilly gives us an example (see the links in the middle paragraph) of how the PerlMonks community almost failed due to a clique engaging in and promoting bad behavior. The reality is that it is inevitable that communities will define what is acceptable, unacceptable, forms of etiquette, etc. and that makes your agnostic view on behavior untenable.

And we are seeing this in practice right now. People are discussing what some consider to be undesirable behavior, people are voting (or not voting) on nodes related to said discussion, voting (or not) on consideration of nodes related to said discussion, etc.

Update: Fixed "example" link. Thanks ELISHEVA!!
