He has some hits up: https://www.mturk.com/mturk/searchb...archWords=David+Nadeau&minReward=0.00&x=0&y=0 for $0.15. I had a few issues finding some of these. Only one review, so who knows.
I did 3 of these. The search engines he points to are brutal. They return lots of Facebook and Twitter pages but not what he was looking for. One had an advanced search to supposedly exclude Facebook or any other site. I couldn't get it to work. If he was trying to prove that the search engines are useless, then he succeeded. I got frustrated and moved on. It sounds like you actually found something.
