It looks nice, aesthetically speaking. It's ironic it declares itself to be semantic, but then tells you to use a link when you need an inline button. I'm guessing because, by default, their buttons are 100% width, which is a really weird default if you ask me. Also, there are no button or form element sizes? This is essential IMO for anything other than a simple login form.
