I use one. Not so much regularly but there is a machine plugged into the wall in my bedroom.
I bought an ASR 33 in 2013 and a few years I designed and built an all-in-one modem interface
that made it onto hackaday. Currently I can dial into remote systems over the phone albeit only at 110bps because more modern BBS's require at least 300bps and I've never had the time to complete a line buffer.
I had it in the other room last month playing Lander on an AltairClone.
