This truly feels like https://www.aleksandra.codes/tech-content-consumer/, where every blog post rehashes the well tread territory of Hugo/Jenkins/Netlify/GH Pages or Wordpress/Blogger/Ghost/Medium/Neocities, or even the newish "minimal" ones like https://news.ycombinator.com/item?id=23313196. You can even blog to specific audiences with the rise of "send a newsletter" SaaS things!
IMO, very few people are at a loss on "where to blog" or "how to blog", but rather actually writing. If you're a dev, you've got text files you can serve (or convert to html). If you're a non-tech person, you've got a dearth of places to blog on, with nearly a decade of tutorials about how to setup a domain and site. It feels like the demand for these "where to blog" posts are mostly to bikeshed on the tools and not actually the writing part.
