Making an X profile match the work you do
Most X bios I read list job titles. When I decide whether to follow someone back, I look at their last ten posts and replies, and I check whether they talk about the thing their bio says they do.
So I try to keep a rough mix: a few posts from my own work each week, and a lot of replies to people in the same field where I add something I learned the hard way. That way the profile matches the bio without me having to repeat it.
