Svbtle: Open for Everyone blog.svbtle.com

Dustin Curtis has opened signups for his blogging platform:

Svbtle is designed to highlight the things that matter; it’s an extremely simple platform for collecting and developing ideas, sharing them with the world, and reading them. That’s it. We’ve focused all of our energy into designing the simplest interface possible for accomplishing these goals. Svbtle is blogging with everything else stripped away.

Svbtle and Medium are extraordinarily similar, and I’m not sure I understand either of them. Are they user-generated publications? Are they like WordPress.com (as opposed to the .org package) but with a cooler interface?
