The online coupon market has been exploding in the last year or so. Just look at some of the startups offering this service: Groupon, LivingSocial, Scoutmob, OpenTable, zozi, SCVNGR LevelUp, viagogo, Google Offers and many others.
Hardly a day goes by without new estimates of what popular privately held online companies may be worth. Facebook at $75 billion? Groupon with a value of $25 billion? Nearly $10 billion apiece for Zynga and Twitter? It's tough to not look at these "guess-timates" and proclaim that there is a huge bubble in the making in the social startup arena.
