CPanel has a great 1 click installer. It just works out of the box.
Things I like about it are markdown support, and... that's pretty much it. I'm kind of underwhelmed by it.
No comment system, I had to tack Disqus on to the handlebars template file.
No statistics? It's a planned feature, but I feel like this should have been like priority one. Bloggers like to see that people are reading their material.
Slow despite being so light in features. This one suprised me; the page is so miniscule in feature that I wonder why it's taking so long to render blog pages.
No syntax highlighting built into the markdown for code support. :(
I feel like Ghost has tremendous potential but it's just underwhelming in it's current state. It's landing page marketing is fantastic, hell it got me to use it, but once I had it I was like: "is this it?"
