I read your text in the context of NvyUs comment where he said "in a community you have no say who moves next door or over the road you just learn to live with them and get along. you can't manufacture your idea's of who belongs here and who does not its just plain protectionism and elitism." your reply started: "Comparing a forum to a live neighborhood is flawed anyway. There are gated communities and other elements in real life that serve to create homogenous communities. In addition, gated communities on the internet can easily narrow membership to a select constituency." I understood this as implying creating a gated, homogenous community would be preferable. The reason I interpreted it as such was your first sentence, where you disagreed with NvyUs analogy of a live neighbourhood. So now you know how I misinterpreted you. I did see later that you were talking about several distinct communities under the same umbrella, and it is useful to discuss it. I agree with you on both those points. I read your link, and if you read mine, there are a couple of commonalities.
