Social media activity seems to be really bad for certain kinds of content. On Twitter I frequently see art posts with thousands of likes and less than 10 comments. And inevitably a few of those replies will be pussy-in-bio spam bots. Even on Threads, accounts with hundreds of thousands of followers often end up getting between 10 and 20 comments as well.
It seems like if you want engagement you have to post some sort of bait content to encourage people to reply. This is often controversial stuff which gets people fired up, or some culture war nonsense.
The Internet was supposed to make us feel more connected than ever but it increasingly feels like whatever you create ends up being a shout into the void.
If you're sharing content that's primarily outside of the main platform, it often won't get as much reach as platform-native content. That's why every big creator always ends up making their own newsletter, in order to have a way to directly connect with people.
