I'm not sure, once they go into monitization they might end up just like yelp.. not showing the good stuff because the businesses did not pay the ever increasing fees.

[quote] “Small businesses don’t want to pay for an ad from Yelp or deals on Foursquare or Groupon,” says Seirafi-Pour. “They have deals already. What they want is a better way to distribute them." [/quote]

I do not see this statement as a 'we will not extort the businesses once our system is rolling'

Full disclosure: I dislike yelp, and feel it's an extortion service. Once the delivery end is kicking, i foresee a class action lawsuit for slander.
