If it's supposed to be an ad for Genius, it's a pretty lousy one, in my opinion. Half of the time I click on a highlighted line, it opens the annotation and then scrolls away, so I can't see it. It's pretty frustrating. And the "view on Genius" link redirects to the top-level Genius.com page, which just makes me sigh and close the window.
Doesn't matter. People will be like "Oh! John Resig uses Genius! Looks like that's actually real software for the cools guys, not some stuff nobody uses."
naah..its only for sometime. Agreed that people surely gonna have a look on it since JOHN RESIG uses it but usability only helps you to keep on using it.
