The entire point of trying to copy Groupon is that they want to diversify their revenue stream, rather than relying on a single cash cow. Defending the cash cow at the expense of future growth would be a short-sighted strategy. I agree that they should devote more resources to fixing this problem, but I would rather those resources come from more established underperforming products, rather than new opportunities.
