Digsby passes 1 million users, pays you $1 to add more

Digsby, which ties your social networking, instant messaging and e-mail accounts into one interface, just passed 1 million users and started an affiliate program yesterday that pays fans $1 for every new user they sign up. Digsby says its average revenue per user exceeds the cost of finding new ones through the program, so the program generates cash flow. Users sign up on Digsby’s site and then use banners, links and buttons to promote the service.
