What exactly are they optimizing or testing for here? Just number of searches, or clicks on that feature. Have they eliminated that people might be clicking on all these odd ball changes because its novel? I know I've expanded some menus and clicked on stuff and hovered over shit I wouldn't normally just because these changes were all shiny and I wanted to see what they do.

But in the end, the only change I like is the logo. Everything just looks a little odd. But my only real gripe is the location of the search results. Is it just me, or have the serps been left justified or were they much more in the center of the screen before? Every friggin machine is getting wide monitors, so to make stuff go left these days and just give me all this whitespace in the center and the right, makes me a little nuts.
