There is a bit of a trend on micro.blog to use Blot for longer form blog hosting. I’ve not dug in too deeply largely because it seemed to put Dropbox in the middle of everything, and my initial impression was that it would be a bit too simplistic. Blot has added
git support as an option outside of Dropbox, and I really like how they did it. Your Blot site is a Git repo by itself, so there is no dependency on GitHub. If you add an iOS app like Working Copy to the mix you can have robust editing on mobile as well. My other concern about being overly simple is just good user experience. There is a lot of power where you need it, but you don’t have to dig through it all to get the basics.
I’m going to give this a go as well. For some of my sites, particularly my photography one, I think this might be a very good fit.
