“Trading Goddess”, who blogs about Wall Street, has written a piece about Why We Will Never Know Why The Sky Is Blue.

She laments the passing of Google answers, commenting in passing that it will be difficult for her daughter to complete her homework questions without being able to ask Google Answers.

More to the point, she reveals the reason why Google terminated the Google Answers service. There were real problems with some of the questions being submitted.
