I explained it in my last post. It is the ease of getting started. You can just copy Ospari on your server and start to blog. Installing Ghost is not easy.
Second it is also about alternatives. Why Ycombinator started HN, although reddit existed?
Ghost and WordPress offer hosted blogs as well as source code. It's no longer necessary to worry about servers or FTP details just to get up and running. Creating a blog is now as easy as filling out a form on a website and clicking submit.
Your only other USP appears to be the ability to parse themes designed for a different engine. Is this going to be enough to distinguish Ospari from your competitors? Is it feasible for someone to write a WordPress plugin that achieves the same thing?
Ghost is great. Wordpress is not.
Yes, currently our USP is parsing ghost themes. Ospari is faster than Wordpress and I would say even more secure than Wordpress. Not to mention the code quality ;-) and we have just released the first version.
