I've always struggled to understand how Fidonet (and BBSes) was different to Usenet. From what I gathered, Usenet was a decentralised network from the start, whereas BBSes were distinct communities and Fidonet was a solution to connect these communities together. I believe Usenet also runs on TCP/IP, unlike BBSes which you dialed into. Can anyone shed some light on the above?

Usenet didn't start out by running over TCP/IP.
