David Hegarty's startup, Hollrr, was featured in Southwest Magazine's Spirit this month. The service makes it easy to aggregate and share your favorite products. Here's a great explanation of one of the hidden perks of Hollrr.
"lots of companies offer affiliate programs, and Hollrr ties in with them. We collect money on behalf of the “tribe” that spreads the word about a product and then pay out rewards based on how the recommendations do. If you’re one of the first to recognize a great new product, you’ll get a larger share of the reward."
