A poll answers where the people voting like to read, so it's worth running the same question where your projects' users are. I'd split it by audience: project updates belong next to each project, as a changelog on its own page plus a post where its users already talk, while the personal blog goes somewhere you own, a site or newsletter, so readers follow you rather than a feed. Then share excerpts elsewhere that link back.
I make ThreadFox. Your AI researches, writes and publishes Reddit outreach from your Chrome within a job you authorize. The free plan for Reddit for your project lists the communities whose rules allow a post about it, each rule quoted:

What are the projects, and who are they for?
