It's me, not you, Allo. I loathe communication apps that rely only on phone numbers and won't work without access to one's contacts/address book. My phone number is highly important to me from a privacy angle and I don't give it away willy-nilly. I'd feel a little more comfortable when this works with email addresses alone, which I have many of and use different ones for different purposes.
