Getting users 
icey: Bribery.Every product launch I've been a part of has basically used some form of bribery to get users. Of course, my background is all enterprise software. We have either shown people how they are losing money by not using our product or how they will miss out on making money by not using our product. Maybe bribery is the wrong word. What's the word for bribing people with their own money?I haven't had any "viral" products yet, so I'd personally like to hear about how that works for people :D
