I wanted to host my blog on a platform which is not tied to a single backend or stack, is dev friendly(git push deploys your app etc) and has a copious free tier. Also, ability to tweak around the look and feel and no-fluff things like markdown were attractive prospects. Openshift seems like a good fit and can't complain so far. Oh, and did I mention its dev-friendly too? Ghost comes to mind when I think of a no-fluff blogging platform.
