Looks like two services that I've been looking at are closing. Ghostify and Roon. Both are markdown based minimalist just blogging solutions. Ghostify was a third-party Ghost host, while Roon was totally independent and pretty nice (even has an accompanying iOS). Both will be gone by 2015.
However, that's not really the end of the story for Roon, as it was acquired by the Ghost Foundation, makers of the open source Ghost blogging API and Ghost Pro, the premium (official) hosted service. Hopefully, the innovations of Roon will be included in the next release of Ghost, and the new team members will help speed up the version 1.0 release.
While I've enjoyed playing with Ghost, it just isn't complete enough. So it looks like Posthaven will be my go-to personal (random) blog for now.
I just wish that they'd release an iOS app, too. The Safari browser post edit interface just isn't that great, though it is functional.
