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?
I would say that there is no need to throttle your growth while in beta. That being said you should definitely have ramp up strategies, and predefined metric levels to know when to execute which strategy. It is critical to your brand to make sure that you can keep up with demand. Too much demand is a good problem to have until your servers go down and stay down.
