The reason we dont have this today, imo, is because forum software is largely developed as premium, enterprise-first software and no longer for hobbyists to congregate (not to say that doesnt happen anymore, just a much larger lift for an archaic medium than before)
Also gotta compete with Discord for that. Which is hard! But is being done in the foss space.
@shiburizu "here's my view which almost, but not quite, entirely unrelated to what you were talking about" is certainly a take you can have, yes.
we don't have platforms for ttrpgs anymore because the concept of a singular platform for a niche is largely dead. reddit's entire business is countering that. i think its pretty relevant!

@shiburizu The sound you heard was the point flying over your head.

I'm not talking about the TTRPG market or what market saturation looks like, I'm talking about horizontal versus vertical analysis of a protocol and the applications that have found their way into that protocol's space.

"But no one would work on it" or "there's not enough demand" or whatever else are completely irrelevant and besides the point. I'm not talking about if there is "enough" interest or whatever, I'm talking about development, _on an open protocol_, _with open source software_, of community-built specialist tools that segregate by semantic type rather than media format.

Also, as a LARP organizer I'd argue that your fundamental analysis here is incorrect, but I'm not going to get into that because it isn't relevant to what I'm talking about.

I think the answer to your "why" is simply that people asked for a microblogging platform, because social media trended toward removing that semantic distinction as a visible limitation a long time ago. The platforms that inspired popular AP projects today were using recommendation algorithms and social graphs to create those delineations instead of making more meaningfully visible separations.

I also think that, as an organizer, "meeting them where they are" is pretty valuable. I spend a lot of time curating social presences I don't personally care for because I meet a lot of people who had "no idea there was something in my area".
