Secession is the rule in virtual space. The Protestant principle rules: Set up your own place and community if you don't like ours. No conversation is obligatory. There is no scarcity of virtual "land" to prevent an endless exfoliation of new communities. Because there's always more room, there is no forced proximity demanding that you overhear the neighbors or meet them on the street. Communities can fraction, break off and each fill their own space. Some may be overlapping but many move out of contact. It's happening with magazines and cable channels as well. Segment the agora.

Yet even with that separation, you can't avoid politics and economics, because there are always some scarce resources. I may not have to see your virtual world or overhear your community conversation, but we all share concerns about the capacity of Internet connections and the state of computer equipment. Real world scarcities can force debate among separated virtual communities.
