All my favorite niches have gone to Discord.
Freaking Discord. A black hole where anything useful is buried under mountains of folks shooting the breeze. Oh, and with a useless search function.
Every. Single. Niche. Even self-hosting ones like localllama.
Reddit may be dead and enshittified, but at least it was accessible to search engines :(
Hardly matters though, as they just randomly shadowban me anyway...
