alt Hacker NewsYa, back when 'we' were fucking around on BBS's there was the equivalent of 10 people online at the time.
Quantity is a quality in itself. Your BBS was never going to support a million users. Once people figured out the network effect it was over for the masses. They went where the people are, and we've all suffered since.
Honestly, I still prefer webboards, the closest thing to a BBS, for specific topics like specific car brands/models. WAY better signal-to-noise ratio. Alas, for my car model, all the recent stuff has moved to Fbook. FML.
