I was expecting a) a blog post, and b) from the .html-ending a hypertext document, maybe with text and images?
What possible reason could there be for this to be "an app"? It's a blog, it's for reading -- and you already need a reader to access it -- why would you implement a (new) rendering engine?
Ok, I can see an argument for adding comments via javascript and a service, or for posting blog posts and doing admin stuff. But the other reasons (user tracking etc) for having this as "an app" only detracts from the readers experience.
