I have no idea what modern forum infrastructure or hosting options are like nowadays, but what if we all helped put together one together with threads and sections focused on some of the most popular tags?
I'm imagining a place that could be potentially a less toxic something awful or resetera. Something that carries on the spirit of this place and allows for both long form and short form posts. It probably wouldn't grow, or have the same sort of image/audio hosting, but still.
Would that be something folks would be interested in? Do you think something like that would be worth looking into?
Edit: doing research...

Edit 2: Ok it looks like there's definitely a lot of interest in something like this. In terms of hosting there appears to be a tons of options ranging from free to paid. I think later today/this week I will set up a discord for folks interested and try to organize it's channels in terms of platforms, community guidelines, and everything that a community might need discuss. Gosh, I get to put my union organizer training to good use, I guess.
Edit 3: I have created a planning discord for this!

Since this is a public post I have an extra step to try to verify people as actual cohost users. It's manual though, so it might take me a while to get everyone who's interested in the planning stage in.
