I'm pretty sure there are "Groupon for X" companies in YC. So clearly people see that there is money to be made. I'm not exactly sure why everyone is hating on Groupon. Why not hate on Zynga for coping other games? Why not hate on Linked In's 500 P/E IPO that has already lost 25% off it's high? The daily deal marketplace may not end up being a winner-take all market. But will having the biggest subscriber list give Groupon an advantage? Once they flip the switch from growth mode to profit mode, who knows what might happen? I assume the hate is mostly just misdirected jealousy because it seems "so obvious anyone could do it." But like Andrew Chen's recent post, it's not easy to build both your consumer side and your merchant side. Anecdotally, I've heard many of the top 10 deal sites have trouble lining up their next day's deal. While the daily deal industry is far from perfect yet, Groupon certainly unlocked a space that a lot of people are jumping into. And I assume that someone will figure out how to do it right for both merchants and consumers in a profitable, sustainable way.
