I'm the downvoted poster above, and I used to run a BBS. Mostly hosting info files and CP/M software (Thanks U.S. Robotics, couldn't have done it without HST). I am genuinely interested in know where (and if) such a network of people could ever exist again. For those who may be too young to get the joke... Reddit is certainly not it.
One major thing missing with Reddit is the focus on geographic locality. BBSes had more of a community feel because 99% of the users were local, and this was enforced by financial reality. Few people in the 80's or 90's wanted to call long distance, unless they were distributing warez at someone else's expense (in which case they probably weren't reading and posting messages anyway!)
You can get "some" of this feel from the state / city focused subreddits... but... it's still not the same.
Some FidoNet boards did, actually! The FidoNet boards near me all carried "regional" forums / echoes that were available only within the regional network itself. I was actually way more active on those forums than the global ones.
(By "active", I mainly mean participating in flame wars. If any of those sysops are reading, I do apologize for the behavior of my teenage self.)
