The problem with feeds rn is that a lot of people actually want subreddits. They want to post to a specific feed with an audience that might not know them directly. You can see that with the science feed and others
I feel that that the twitter social media archetype is good for personalities, but is kinda bad for gathering low-follow-count ppl around a specific topic. The Reddit archetype is very bad for personalities but great for interests and communities. 0-follower twitter feels like posting into the void
