A couple days ago, I wrote to Google's new "Question and Answers" service (it was in beta mode; the link now says they're currently not accepting questions). I asked, "How much are you getting paid (per hour) to answer these questions?"
Today, I got my emailed response:
"We appreciate your interest in the business aspects of Google's Question and Answers. Unfortunately, due to the nature of your question, we are unable to answer it at this time. Your credit card will not be charged."
