Thanks for the tip! I thought something like this probably exists, but didn’t have energy to look it up after the installation fatigue. I’m not quite yet decided whether I want to add communities manually or automate it, I’ll probably first see whether I’ll add a couple of friends to the instance or not, and what they might think.
Even if I don’t add anyone to the instance, using All as a type of custom feed would be an option too, adding communities more liberally than I would for Subscribed… Perhaps the way Lemmy does this isn’t as bad as I first thought!
One thing that might not be obvious is that the All feed is different too, as it only shows posts from communities someone on the instance has subscribed to. But since there are ways to search communities across instances, it isn’t really a big deal. Unless you’re on an instance of one or two people maybe.
Federation and moderation are probably where the instance matters most. Also, the matter of who runs the instance is kind of important considering stability and longevity of the instance. (mine for example will probably be gone within a month once I break something)
