Agreed. I'd prefer to discuss the pros/cons of the framework, but honestly the content on the left was enough to make me stop reading. It's unfortunately very common to miss out on interesting content because of UI pickiness.
There was a link posted on reddit about this framework, however it linked to a nodejitsu blog post, and iirc, nodejitsu links cannot be submitted to hackernews.
I'm viewing this on an iPhone via the news.yc app, and the website is impossible to view on a mobile browser. Op might want to look into that.
Same problem on my iPad but I found the solution: use 2 fingers to scroll.
Viewing this on a netbook is a nightmare.
On another note, when will they launch? I got an email a while ago announcing the beta but never let me sign up.
