Of all the naysayers, the Hacker News community seemed to be one of the most consistent. I'm curious why that is? Is it because Groupon doesn't look ostensibly too technical? Is it a general disdain for commercial success? Is it for perceived arrogance? Is it a lack of business acumen?
On the flipside, their customers (merchants) are reporting that they do not see the conversion rates that Groupon advertises to lure them into a deal. In response, they try things like raise their prices prior to honoring a deal, which further dilutes the value of Groupon's product.
