What does the group buying trend mean for small businesses? Is it time to pay attention or too early to get excited?
In some ways, the situation is similar to how small businesses might consider involvement with another emerging trend: location-based check-in services like Foursquare. Neither trend has reached the critical participation stage, but both have advantages depending on the nature of your business and clientele.
Group buying in my opinion, especially with location and friend aware presence will do to shopping what eBay and Craigslist did for it in the 1.0 days.
