Great idea. It could definitely gain traction in other niche markets as well, including SaaS (i.e. retweet for a discounted initial monthly fee). All the best of luck!
I really like this idea and the simple execution of the sharing functionality. Since it's free, how do you plan to make money? And how's your infrastructure if this were added to a high-trafficked site?
Great idea for bringing more relevancy to social and ecommerce.<p>We have this up and running on www.FairWayStyles.com. Increased both user engagement and conversions.
