2. Whenever I find the time, somewhere between a few times a week and twice a year, depending on lots of other circumstances.
3. Self-hosted (via azure & cloudflare) HTML generated from markdown files using a fun little utility I built as a learning project (all the generator code, markdown, & HTML is stashed on GH: https://github.com/mplanchard/speedy). For whatever reason I'm more motivated to maintain something I've built myself as compared to previous attempts with medium and such. The freedom to do whatever I want, however I want is nice. I can present things simply, with little to no adornment, avoid pushing trackers and ads on people, explicitly release my content under whatever copyright I want, etc. So far I've yet to incur any costs beyond Azure's free plan, but while it's been free so far, I'd gladly pay a bit of money to continue to keep it under my control.
