Dunno if this interests you at all, but I would gladly pay for this. A minimal blogging service which handles hosting, export of data (if needed), and basic styling is something I've been looking for for awhile. All the large platforms feel way too bloated and complicated.

Just made an account and excited to try it out, but if you ever decide to charge folks, you wouldn't lose me! Also just seeing that you say some folks sponsor the project; I'll take a look at that!
