In response to my blog post about being a creator and not a consumer, let me write about my results of using Amazon Turk for the first time.
The original batch was for an HIT of 100 assignments at $0.15/each. After 24 hours, there were no takers. So I reduced the HIT assignments to 20 @ $0.30/each. Within 2 days they were all completed. I approved them all without reviewing them, downloaded the CSV, and uploaded it to Google Docs as a spreadsheet.
