Tumblr was awful for Discourse™️, there are some legendary headass takes originating from there. A lot of those people moved to Twitter after the Tumblr porn ban, and it slowly has gotten less insufferable.
I'm really surprised that people don't make the connection that Twitter Discourse™️ is Tumblr Discourse™️ but short form. I genuinely think Twitter got magnitudes worse after the Tumblr migration, especially if you're on the music/media/fandom side.
