Releasing a social app in the coming weeks which utilizes Network Effects and Groups of Friends. For the Beta, we have identified specific groups of friends we want to test the app on. However, should we limit their individual ability to invite friends to join the app?
Don't focus on the quantity but in the value you provide. Numbers ca confuse you to think you have "high demand" in beta, to later launch and fall short. Or launch with no beta traction to later find your core users and go viral.
The metric is not in the numbers but in the value you provide. As Paul Buchheit said "is better to build something a small number of users love than something a lot of users like"
