Well the main page is good but the search results are still overcrowded. The hover-effect on the search results is distracting. It just diverts attention from the results. I doubt many people really read like this: "hover mouse over first result: Not it. Ok, up to the next one: Hover mouse over second result. Not it. Ok next one."

Then of course, it bothers me that I have to pay attention to where I click, and if I want to copy paste text, I have to be exact about it, otherwise I accidentally click on whitespace that will direct me to a result page.

It's just too much "cognitive work" associated with the UI.
