BBS's back in the day just had a hell of a sense of community to them, for me. The sysop behind the screen generally put a lot of hours into making his (or her) system appealing to the general public, and usually spent a good chunk of change running the damned thing in the process. Modern forums lack the personality for the most part, but no doubt are easier to use. People that didn't cut their teeth on BBS's prior to the 'net generally don't "get" the BBS concept at all and just say stuff like "why would I play Hack & Slash when I can fire up Crysis or CoD?". Point is well made on their part, tbh, lol.
The Amiga sysop community was very strong way back when. Sadly, since I got back into the Amiga a few years back, I have found that to have entirely gone away. It's atrocious even amongst sysops here on A.org. Way back when it was common for sysops to help each other out with software, and I've been waiting well over a year to hear back about one certain BBS package that's still being worked on, even after offering to pay for it a second time. Dev and sysops of the one well known Amiga BBS program are absolutely of no help at all, so I stuck with running what I ran back in the mid 90's (Zeus BBS, runs OK on my SAM 440/4.1 rig).
The Windows/Linux (Synchronet specifically) BBS community is very strong and I'm seeing a lot of Amiga BBS themed sysops simply considering running it rather than Amiga based systems. Synchronet is a stunning piece of software if you can get past the fact it's not Amiga based. Just something dirty feeling about running an Amiga themed BBS on a PC/Windows, lol.
