I guess I don't do it much anymore (posting on forums like this notwithstanding), but I'm not sure I've changed my mind overall. There's a certain kind of community that BBSs, along with medium-sized Usenet groups / webforums / mailing lists / etc. gave, that is somewhat different from IRL kinds of communities, and also different from both very small online communities (people you already know) and very large online communities (places like reddit, Slashdot, and HN). Not to promote a replacement of rl with cyberspace, but I think it's an interesting experiment where something is lost by it not persisting.
