Thank You! Honestly I think one of the things I like a lot about lemmy, and the fediverse, is the ability to easily block users, communities, and whole instances I don’t want to interact with a all. Everytime someone complains about seeing too many foreign meme or whatever I wonder if they have tried the blocking features to trim down the timeline.
Have you checked out Mastodon? Idk if it’s exactly what you are looking for since it’s more akin to Twitter but it has hashtags that you can pin to keep up on. There’s some stuff that’s more longform and visual on there too or at least people will link to there stuff if it isn’t listed there. Maybe try a couple different apps, I use megalodon, see if does what you need.
