Used it a fair bit; gets expensive, and you get what you pay for, unless you spend a fair amount of money (some people have trouble being honest- maybe they're in too much a hurry). You can opt to not pay people who don't do the job, and that usually involves sewing in secret tests and checks to find out who those people are. Surprisingly, most turkers (laborers) are US or India based. You can limit by country, or even by state. They average in the 30's, and run the gamut from ~40% full time turkers to janitors to security guards to police to teachers to attorneys and physicians. Many are high school or less, many college-educated. Happy to answer any more detailed questions.
