I feel like there's potentially a market for a general forum that provides the ability for anyone to create subforums, the same way Reddit has subreddits. Obviously you'd need something more advanced than the usual complete subforum list as the main page. Big forums like SomethingAwful already have may subforums for different interests, and letting people create subforums seems like a logical next step from that. You could create ones for interests, or even for your business so you don't have to set up your own forum. If it seems weird to have a subforum for a business inside a larger forum, well, people already do exactly that on Facebook and Reddit. Reddit provides something similar to the same thing, but the format doesn't work well for long term or chronological discussions. Maybe the time for traditional forums has been and gone, but I'm not so sure.
