I have an app that lets users mail postcards to their friends. Open app, see friend list, pick friend, enter address, mail card. This idea no longer works (and has to rely upon phone contacts.)
There are a million other ideas like this that aren't spammy/unethical/evil. This was basically the main pitch Zuck et al made for the API when it was launched, that you could bring in your friends and make your apps social. It's hard to imagine a way to bootstrap an app up from nothing if you have no way of knowing who the user might want to socialize with in the first place.
Yup. I have this principle of never investing in or building on a closed ecosystem. This means I miss on a lot, but ultimately all of these services go down with no regard to your business.
