I've recently done the same. Had a dormant firstname+lastname twitter profile for years. But made a new one for a niche a few months ago. Only follow and interact related to that niche, and I get lots of engagement on the stuff I post. 900+ followers already.

What I think makes a difference is that the name of my account tells what you can expect. So if someone sees a comment from me, the chance of them following me is higher as they know I will only post related stuff, compared to following some random person making a single great comment, and then getting all their other stuff in your feed.

I now also chat regularly on DMs with other people in the niche, get recognized sometimes IRL and end up in conversations based on it etc. So actually been some interesting months.

Edit: I guess this also depends on the niche. For me that niche is just a hobby, which means that most of my interactions are pleasant. So pretty different experience compared to if one's following controversial topics/figures.
