Isn't the chart on the top of the page misleading? I think just about anyone would think on first glance that Groupon's revenue had ~tripled month-over-month.
Groupon, by the nature of it's business takes in a lot of revenue. But it doesn't keep most of it. Much of that money is paid out to the business running the promotion. Maybe someone else knows the approximate split?<p>Revenue has some bearing on Groupon's ability to generate profit, but revenue is a vanity metric.
