I've played around with an install and ran a blog on it for a bit, and was never too impressed. The functionality and features all seem simplistic (Which isn't a bad thing in itself), but made me wonder why I had to download what felt like hundreds of packages with npm when I installed it.
Even with all of the features they promised in the kickstarter that have now been cut, I never quite understood why they needed so much funding to create the project.
I hope they are able to do better in the future, if only to have a good alternative to WordPress, and to maybe deliver on things that they have shelved.
Edit: Looks like ghost has 38 direct dependencies in NPM, of which many have their own dependencies, etc.
