Twilio Phone Number Authentication

It's important to not "corrupt" your social graph. Only offer phone number verification, since this is what people use for their contact books. If you add another method of signup then you won't be able to efficiently calculate who knows who, who might want to know eachother, and so forth. This is where most people mess up on day one
