I guess I really don't understand this part of what you wrote:

it may hurt businesses over the long term even if it provides some short term gains.

On their website for businesses, Groupon markets themselves as a sort of loss leader, hurting businesses in the short term, to help them in the long run. Are you thinking that businesses have such huge markups that they make a profit on 1/4 of their usual asking price, and this is letting people in on that secret?

Also, I'd like to know if you've worked with Groupon, if you own a business, or if this is conjecture on your part. I don't have a business, but from what I've read, I don't understand where you're coming from.
