You're right, I didn't get a ton of responses. Still, the responses I did get were overwhelmingly pro-Groupon. As someone seeking an answer to an important question, my takeaway was "Hm, HN thinks it's a good idea." Honestly, I'm still on the fence. I've said this elsewhere, but I'm in China and the Groupon clone market here is really saturated and interesting to watch. Basically, the Chinese clone market really resembled the American market for a while (w/ a winner, Meituan, pulling ahead), but then just about every site with a large email list or userbase joined the fray. Even my local expat magazine is running a Groupon clone. The original players are now getting clobbered by RenRen (a Chinese Facebook) and Dianping (the Chinese Yelp). I can tell because I know a Groupon clone owner who's basically dropped out of the contest and because the other clone salespeople (including Meituan's) have become increasingly desperate and have offered me increasingly better terms. I'm currently leaning towards using some of them, because I believe I've gotten some of them to the point where I can have the Groupon require customers to buy from my website, which gives me customer information that I really want. Customer data aside, I still think these sites are causing the equivalent of a price war in the industries they're targeting. During some periods when a competitor is being featured, it almost seems like it's directly hurting my volume. I guess it could be coincidence though.
