I don't actually think I mentioned using Pelican, which I switched to after Ruby. I hate Ruby. I didn't hate Python, but given the chance to use Swift instead why wouldn't I switch? Having the ability to use only Xcode and git is fantastic.
It's very easy to set up, at least as easy as Jekyll or Pelican. It's totally easy to convert old blogs. I chose to rearrange images somewhat so converting absolutely everything, including fixing up some images and typos, took just a few hours. If you have an interest take a look, I think you will like it.
Obviously this is pretty vanilla right now because I have read nothing but the github page, but I think it's got a lot of potential.
