As I would love to move my blog away from Blogger I took the first step towards that and wrote a converter. blogger2ghost simply takes data provided by Blogger and munges it into Ghost compatible format. Simple as that.
Ghost advertises itself as a new age blog. It has been implemented in Node.js and features a very nice Markdown editor. The platform is still very much work in progress but surpasses Blogger in many ways. And it looks nicer too.
In case you are on Blogger and want to give Ghost a go, maybe this is your chance. It won't solve all your issues. I still have to set up Disqus work on Ghost and migrate the comments there and you might run into similar problems.
