It works well in Chrome, and it seems quite user-friendly. It looks like the posts/actual site won't really load—or they partially load. But the story editing, etc works well— just maybe focus on the UX a touch—make publishing the post easier to find.
Now for the stuff that always bothers me about decentralized publishing platforms like this—
if nobody can remove or alter your content, what is preventing people from posting harmful content (need I explain)? It also doesn't sound like there's any recourse for removal. It also sounds like you intend to monetize the platform, or at least parts of it. This could render you a provider of paid services to people who wish to find a space for permanently publishing those kinds of materials.
As a comparison, a publishing house would not print child pornography in the name of free speech. They're operating a business— it would be suicide.
I've just never heard a good answer to that one, so I'm curious about your take.
