Ugh, I don't know if it's just me, but browsing for anything on Amazon.com really irks me. First, the page loads, then a bunch of other stuff loads in the background. The problem is that you try scrolling after the page loads, but the web site is so demanding on the browser that it frequently breaks scrolling. Plus, the tab title flickers the entire time this is going on.

It's clearly a symptom of a large number of people working on stuff that all ends up on the same page.
