Set my settings to hide NSFW, blocked most of the “soft” communities like hot girls and moe anime girls and whatever else (blocking the lemmynsfw.cominstance is a great place to start), and I use All frequently. That’s how I’ve found all the communities I’ve subscribed to, but frankly, my /all feed is small enough that I usually see all my subscribed communities anyway.
