I use this directory, which works pretty well. I'll subscribe to anything that looks interesting, then unsubscribe from the ones that end up not working out. On Reddit, I would just search, so hopefully the search improves so I don't need an external resource.

And I personally just search every few weeks or when I want something specific.

What if something interesting happens

Then you miss out. I personally don't have much FOMO, so it's not a big deal for me. Most communities don't have a lot of posts, so it's not hard to get caught up if I'm late by a week or two.

I personally find that I skip over most content when I visit local or all, so it feels like a huge waste of time vs looking at my subscriptions. I don't like a lot of the high volume communities (memes and other similar content), so for me, sifting through a ton of uninteresting (to me) content isn't fun. I'd rather miss a few things than spend tons of time scrolling past things I dislike.

Everyone is different though, and it was just an honest question. If it doesn't work for you, it doesn't work.
