I don’t want random posts to appear in my feed from communities I haven’t subscribed to, but I want to have a feature that shows me suggestions for communities when I ask for it. That’s a big difference. Right now it’s (too) hard to find these communities.
Yes, that’s what I mean by not trivial, a centralized system can do analysis like this a lot easier. But even on your own instance, they could find the N users with the most overlapping subscriptions and check which communities they follow to give you recommendations.
I would like to see recommendations for communities based on my communities. It’s not trivial to solve, but discoverability isn’t great right now.
Crazy, I’m also in Europe and my provider stopped supporting MMS like a year ago
