Simple and useful, very cool.

One thing I thought was interesting as I was clicking around was how so many of the sites have "converged" to a single UI design style, e.g. full screen photo background overlaid with a short blurb about the site, and a big slightly rounded-rectangular "start" button (sometimes some text fields), then as you scroll down you usually get a couple horizontally laid out big icons, etc. etc.

Of course, this isn't surprising, but it just becomes so apparent as you click refresh. Just thought it was interesting, that's all.
