I hadn't thought about it much until now, but you're right. I check all at times, but it isn't as genpop ready as, say, Reddit.

That being said, my subscribed feed is great. The content is pretty good, and so too feel the interactions.

It might be frowned upon by some, but a lot of people could benefit from something like a default subscription list from a sample of instances.

Another QOL thing can be the right app or web app. E.g., Memmy and mlmym.org make the UX solid out of the box. A lot of folks might have to stumble upon those bits of info here, though, as opposed to an "onboarding" process.
