This is an example of one of the great things about the current phase of the Internet; there are virtual communities virtually everywhere, catering for virtually anything. Places to share common values, beliefs and experiences.
Every topic or ideology catered for. From bulletin boards for people who love customising their obsolete Tivos, through sites for fans of Buffy The Vampire Slayer to photo-sharing pools for people who have a passion for garden water butts. You name it, there will be a community out there which is interested in it. The Internet makes it possible for people to come together around the most obscure of common interests.
The Internet is a truly remarkable thing.
