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.
When I was about to go into high school I wanted to learn about cool music that wasn’t just the classic rock my dad was into or top 40 pop music. I knew Pixies were cool because Kurt Cobain said they were cool and I liked Fight Club so I downloaded a copy of Surfer Rosa. That shit changed my life. It was so foundational to my tastes and opened up a whole world of independent music to me. Cloud Nothing’s Attack on Memory was a big deal for me too… I’m gonna miss the dude. Thanks Albini, you made some cool music.
