A couple of days ago Jason from FlightCastr put me on to a new crowd sourcing service PickFu. They charge 5 bucks to get 50 responses to an A/B question. (Who is more provocative Lady Gaga or Madonna?) They then put it out to Amazon's Mechanical Turk and get you 50 responses, each with demographics and a comment. Pretty cool.
Today I came across Eyeka which is like 99 Designs but for ad campaigns. I like the idea of crowd sourcing both the content as well as the decision making. Pretty cool what you can do on the cheap these days.
