If there's a real market for this kind of app, that's great and I hope it does well. But it's not something I would ever use. (This is intended as feedback -- think of me as the type of user you'd have to work hard to win over. Maybe it's a problem you can solve somehow.)
I already have several communication channels available for contacting my friends, and the cost of adding another isn't worth the slight benefit I might get from an app that targets such a specific problem.
In general, instead of managing accounts on 50+ apps, I've reduced most things down to a few spreadsheets and shared documents on Google Docs. It takes so much less effort and mental energy when I can just keep track of everything, however roughly, all in one place.
So, ask yourself, what would make Por Favor the exception to this rule?
