I go to mentalhealthforum.net

The Android rom ones like xda forums are active.

This is definitely not what you’re looking for but college sports forums are active if you want to read the dumbest shit ever.

I’m from Louisiana so I’ll pick on my own team and link to to Tiger Droppings:

The recipe posts are actually good. It’s basically a forum for insane people who get mad about LSU gymnastics recruiting but then post an alligator sauce picante recipe that’s better than anything you’ve ever put in your mouth.

There are so many niche forums.

Here’s one I found a while ago when I was looking at repairing an old electric fan I found: Antique Fan Collector’s Forum.

In the way that people would always add “reddit” to their searches, try just adding “forum”.

Gallifrey Base, sometimes 😌🤓

Isn’t Reddit or Lemmy pretty much just a structured forum?

https://bbs.archlinux.org/ btw

Special interest forums still hold.

For me, the Royal Enfield motorbike forums are exceptionally good, and that’s largely down to the admin. There’s also a Series 2 Land Rover forum that has a unique collection of people with a phenomenal combined knowledge about that car.

I’ve hosted a few in my time - since the early 90s and Fidonet when BBSs were the thing. But things change. Facebook killed of a whole bunch way before Reddit and Lemmy just because that’s where people were already, and it was easier for them to feel involved. Facebook is impossible to search, though, so the post history of a forum that was so useful has gone entirely.

It’s sad, but things change. What’s constant is people’s desire to socialise and discuss topics they are interested in. I’m kind of curious what that will be next.

https://tildes.net/ is still quite active and while the interface is similar to old reddit the focus is more on discussions than sharing links.

Car forums are still somewhat active. There’s usually one per car make or chassis. For example I use zilvia.net for S chassis stuff and miata.net for Miata stuff which are both active.

Excellent forums. I have been a member for five years and it has been fantastic.

tildes seems pretty active

spacebattles as well

and the dwarf fortress forum, too

I know this won’t interest most lemmy users, but the forums for most large american colligate sports programs are alive and well.

The EndeavourOS forum to give support (I use base Arch, but they’re close enough), the Lutris forums, and Blenderartists. Stackoverflow and similar services, and various issue trackers, if you count those.

Spacebattles is still alive.

Nexusmods “forums” and pages still have some social activity.

TBH it’s pretty barren. I noticed that even comment sections are drying up.

This varies a lot by individual, but I have a Newgrounds account and I post to the forums that are there too!
