This is very helpful to those of us who never experienced BBSes.
You can get "some" of this feel from the state / city focused subreddits... but... it's still not the same.
(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.)
The huge win to hooking your BBS up to a FidoNet (or the FidoNet) was that you'd immediately be having conversations with people all over the country.
I'm going to continue to assume that GGP is sincere until its author says it was a joke.
