I've been around online communities since the early days of Listservs, BBS's, Newsgroups, Telnet groups, etc and it has always been niche groups that serve a specific audience. My assumption has always been that it's a very small percentage of people that participate in a community but you always have a ton of lurkers. Social Media, such as Facebook groups, I'm sure have caused traditional forums to decline, online communities will continue to evolve and change but I don't see them going away.
