Lurkers Are Not Part of the Community

Clearly, some things do not foster community. You do not need a real identity, but you need some identity. You need to have a voice, a reputation, a presence to be part of a community, because it is (at least) a two-way propositions. Thus "lurkers," people who only read or listen, are not really part of a community. They may fancy themselves to be, but no one would miss them if they left. They are fans, not friends. Lurkers may latch on to a culture, but they do not contribute to it. (That's why fandom is so eerie: There's usually no real communication between the fans and the stars, just lurkers and fantasies on one side and a PR machine on the other.)

Lurkers are fans, they are not participants; however, they could become participants if the system encourages it, like how Slashdot does with their comment rating system.
