It's definitely weird. I like that kind of load-as-you-scroll mechanic on tumblr sites etc, but it's not so good when you're looking for an image, it just seems less precise even though it's probably still quicker to find what you're after. It's now just like a shit version of Cooliris. Google should just buy out whoever developed Cooliris and find a way to integrate it with browsers a little more fluidly.
