Small fortune from 17:43-20:09?
I guess you couldn't see my tongue in my cheek!

There are complains in the CrowdFlower forum about those low payments.
Perhaps, although it's the "free market" setting those prices. If
no one would work for those wages, then it's likely the going rate would rise. Of course, that kind of work (e.g. determine if this address is a business or a residence) has some, but limited value to the requester. Also, since CrowdFlower asks each question of multiple workers, the individual payment is a fraction of what the requester paid for the question.
Warge should look for alternatives.
Looks like using CrowdFlower provides a stream of questions to be answered, so it has some value. It may be that CrowdFlower evaluates which "labor partners" are best suited for different tasks, and allocates jobs accordingly. If that's the case, then if/as better workers join CoinWorker, better, higher paying jobs will be assigned.
