The discoverability, both from the outside and within is absolute trash, but the closest I find of those old forums nowadays are Discord servers.

Agreed, it’s the discoverability that’s the real problem here at the end of it all. All the veterans are pulling up the drawbridges to protect their communities from trolls, greedy companies, AI scraping, etc. which means new people can’t find them. Which then means these communities eventually whither and stop being helpful resources for us all.
