Hmm, they used Mechanical Turk "workers" to this experiment, paying each worker 40 cents per answer, which netted them 400 responses. They upped the payout to $1 and hit 1000 soon enough. They mixed the two response sets in the final analysis. I'm SURE that didn't skew the results at all. They respond to this in the study, but it's going to take a lot to convince me that Mechanical Turk is a respectable source of subjects for consumer behavior research. The real news here is that Bing and Google are virtually tied with respect to search quality. But that's been my experience based on using DuckDuckGo (which is basically a rebranded Bing afaik).
