@kkarhan @drwho @sabi @BNetzA 2400 was the first "big step", below that just too easy to out-type or out-read. It's also the fastest I could get working over satellite phone relay from the arctic (2-4s latency), quite robust to bad lines or the like.

Past that, everything of course became a bit quicker, but from 1200 -> 2400 on the BBS's for me felt like dial-up -> DSL.
