I just wanted to announce that over the weekend I launched a new BBS titled after my Atari 2600 homebrew, Space Cactus Canyon. You can use your favorite telnet client to access it at spacecactus.sytes.net, or, in the (extremely unlikely, I'm sure) event you don't have a favorite telnet client, I've set up a web page with an embedded client.
It's pretty small right now, but I've done some customization in terms of graphics and forums. As for files, it has some of my favorite DOS games available for download, as well as some Atari 2600 ROM files--official releases and homebrews.
I've never run a BBS before, and this was kind of a "because it's there" type of project. It seems most people run them either a.) out of nostalgia or a desire to keep things old-school or b.) from a libertarian, away-from-prying-eyes perspective. I'm wondering if there's something that BBSes could do today that the modern Internet can't. I don't know if there's an answer for that, but it could be very interesting if there's a service that a BBS could provide that's not really available elsewhere.
Anyway, check it out if you're inclined, and let me know what you think! And I'd love to hear other ideas about what a modern BBS might accomplish.
