They sure do load up some of their pages with ads. They have defended the practice saying that they only do it on some queries, but not on the vast majority of queries. They say they wouldn't penalize a website that had just a few such pages.
I personally use Ad Block Plus anytime I browse the web. Especially on Google, but even on my own site. I don't want to see them. Given the effectiveness of ad blocking and how easy it is to use and set up, it seems to me that if users don't want ads, they won't see them.
