Groupon as a business idea sucked. Anyone who used or tried to use Groupons, even people like me who make really good money but wanted to test the concept, saw immediately that it sucked.

That Groupon was valued at billions, and the guy who founded it still has a net worth of (est.) $200 million is another example of how the stock market has been so perverted that it harms rather than helps the society it was created to serve.
