What features would people want in a social media application?

I'm developing an android and Iphone app which is like Snap Chat. Would anybody suggest any features which they want in the application. I will read all the feedback which i receive and add as much as i can. I will give you alpha and beta to you all who answers. If you wanted i can make a special contribution list on the app which states you helped with the app.

I'd probably not bother, no need to reinvent the wheel an all that. Find something different? As a pose to just (to coin a phrase) "rebuilding Facebook".
