Here's a theory I've been sitting on: X deliberately crippled the group chat and DM functionality to push people toward posting on the main timeline instead. Think about it—when messaging works smoothly, conversations stay private and contained. But once those features get clunky enough, users naturally migrate to public posts where engagement metrics can spike. The algorithm loves activity, and public posts generate way more data points than private chats ever could. Whether it's intentional product strategy or just neglect that happened to achieve the same effect, the result's the same—your feed gets more crowded, and X gets more timeline engagement to work with. Pretty convenient timing if you ask me.
