As someone who turks occasionally, you can't consistently make $7 an hour unless you have some skill that you could probably use on the job marketplace. $3-$4 is more like it.
I can confirm that. The article he cites to support the claim (from 2009) indicates the author made $4 off a 350-500 word article, and $3 for a product review. Based on my experience, those went for about $1.50 and $0.50 as of about a year ago.
$3/hr on Turk is pretty good, and you need some education and diligence to do it.
