Ask HN: Should I separate out my Twitter posting with different accounts?

HN, please help me with a decision that I can't seem to make my mind on. I want to know if I should post about different niches into different twitter accounts.

I like to tweet ML/AI related stuff including papers, and also about stuff related to my blog (which is more about "getting smarter and understanding the world"). These two audiences have only minimal intersection.

I get decent engagement with the former, but not with the latter. For the former, I have a lot of my colleagues and people in the circle following me, which helps. For the latter, I haven't built the audience yet. Based on the followers and engagement it feels like my Twitter is a "work Twitter".

I also feel weird about posting about my blog to my work Twitter. For my blog I think I need to wear a different hat and become a bit of a marketer, which just feels weird. So an option is to separate things out, but that makes it very hard for me to get started from scratch.

Any thoughts?
