I really hope we don't end up on Reddit. Over the years, they are pushing way too hard to force their apps and accounts on you. Seriously, have you tried just browsing the thing? Especially via a mobile browser?
Endless popups, app prompts, content loaded a few posts at a time... sometimes, they just cut you off after a certain point on mobile and tell you to use the app.
This, and any other walled-garden services, are the worst-case scenario imo.
Discord is not much better, and it just sucks as a knowledge base. Searching for answers in the past on there is just bad.
On the other hand, there's a lot to love about this forum: not only is it open enough (with the export) and works as a knowledge base (search! topics!), I think over the years we got ourselves a nice, friendly community. It's not just hyper-nerd techies; but "normal" folks, too! 
I'm not saying this can't be maintained on other platforms, but I'd really hate to risk losing this community.
I can, like, increase my monthly donation by a dollar if it helps.
