I personally think the idea of only providing results from a limited number of "pre-approved" sites is horrible, even if it weeds out some lower quality sites. But, doing a quick Blekko search, I'm seeing plenty of spammy sites. They're obviously using a computer algorithm, even though they say the results are human approved.
