I too started 27 years ago. Thanks for making me feel old. 1999.
Youngster.

I'm not too far beyond that however--I started with a "guestbook" script, and in 1997 set up one of my first forums using WebBBS, which was a spinoff of wwwboard (from a site called, I think, Matt's Scripts?). But I had moderated a CompuServe forum (with others) as a "sysop" prior to that. (A "wizop" was roughly equivalent to an admin, and only the forum owners had that capability.)
It's hard to believe next year in January, I'll have a 30 year old Forum. And the largest I admin will be 25 years old.
Starting a new forum now is much harder than it used to be, mostly because you’re competing with the lazy convenience of Facebook groups, Reddit, Discord, and so on. So you can’t just knock a forum up because a topic “seems popular”. That just won’t work today, unless you get especially lucky with the niche.
Agreed. Some niches can still take off, especially those that can offer some sanity and intelligence beyond what social media and Reddit offer, but it takes a forum admin passion to run it, and enough users disgusted with social media to want to visit.
That is actually key to the longevity of the forums I operate as well as other long-running forums I use as a visitor. It's
not social media, and that's why we like it. We avoid the trolls, flamers, and members who can barely write a sentence. There is far more intelligent conversation on forums than
any social media, in the niches I either admin or use as a visitor.
Regardless, it takes a lot of time to grow a membership base. This has always been the case. And self-promotion without advertising, and without coming across as a spammer, is much more difficult today than it used to be.
