"Follow me on X"
Why... just why? Why do people keep insisting on using it?
The charitable explanation is "because that is where most people are." Network effect is real.
Because that's what he uses. Instead of shaming about using X and going off-topic, don't comment at all or comment something about the project.
Because people like using social media?
"Remember to like, share and subscribe."
Form over followers over function, the 21st century design ethos.
I certainly won't.
I wonder if it's because they don't see other relevant low-cost/overhead solutions. "Follow me on facebook" certainly isn't going to be a win. "Follow me on Bluesky or Mastadon" is going to be ignored. "You can see my comments on insta" won't be relevant. "My TikTok is where it's at" might get you some young followers.
Other solutions (your own blog, medium, substack, etc), all come with more overhead and setup.
