The issue isn't the tool to get your blog up, but hosting it.

The real solution will be a super easy app that lets you push the blog out to:

- git* pages

- digital ocean/vultr/aws/wherever

- netlify/forestry as an advanced feature

- move it easily from one to the other

(You have to set up an account on the target and provide the app with credentials/tokens or whatever).

Setting up markdown-> html+css themes is what everyone focuses on
