See, I don’t believe this. It’s possible the project would die, but so often have popular projects lost their maintainers, and new people step in. They fork it, or have a peaceful transition of ownership, but the project carries on.
With Zusam, I don't think it's got that much of a following yet. I haven't heard of anyone on a self-hosted forum actually using it. Plus current development is slow (last release almost a year ago), so I do think it would die if the dev abandoned it.
Yeah, that was an interesting avenue; I suspect the user client experience will be where that fails for me. It can’t require any technical expertise.
I'm thinking that most of the non-technical people would be reading only, so it might be ok.
At this point I'm thinking of setting up a HumHub, a wiki (maybe Dokuwiki), and Zusam, and getting some of my most interested people in as a trial and see which one they prefer.
None of these options have emoji reactions or gifycat integration, though.
The Steam page just says Windows. ProtonDB has no reports.
However, there is a demo, so maybe someone can try it.
