Yes, lots of people do it. There is a "Greenkeys" mailing list
http://mailman.qth.net/mailman/listinfo/greenkeys
populated by mostly ham radio RTTY types, but it's also a great archive
of posts about hook-ups and repairs. Yes, there are current-loop
adapters and RS-232 to USB adapters that can be used to connect
to contemporary machines. There are also streaming audio web sites
that send RTTY-style signals if you'd like to emulate your old radio
over the Internet but still use your RTTY audio decoding hardware.
There's also a fellow http://aetherltd.com/ who connects even older teletype
hardware to cell-phone texting.
The Teletype Model 33 was very popular among early computer users
because it was relatively low-priced compared to heavier-duty
teletypes. The old RTTY folks tend to look down their nose at it
because it wasn't as robust as other models.
They routinely huff and puff at recent auction prices for the Model 33,
though, as old computer collectors routinely pay $1,000 for them, while
it's tough to give away the better-built (and heavier!) teletypes.
Last summer I picked up a Western Union-branded Teletype Model 28 KSR
(circa mid-1950s) in near-pristine condition for $50. Almost twenty
years ago I found a Model 33 in a university dumpster.
