Featured on BetaList! Creating viral loops on traffic.

So Holler Away got featured on BetaList (https://twitter.com/BetaList/status/1271993727117123585). I've re-shared it on other social platforms as well. At the same time, I had 1 month to plan for this feature, and I've updated the app to include social login, gifs and videos support in my chat functionality.

I'm planning to include viral loops, like encouraging people to invite friends to join the app in return for more "feature" points that they can use to advertise their hollers on more prominent areas of my website.

What are other innovative viral loops that the community will recommend for today's social apps?
