Indeed, I have as many phone numbers as emails if not more. Further, I'd be very wary to subscribe to a service using a phone number given the total lack of anonymity with them. On the other hand, having several email for the various facets of our lives can match perfectly with the various uses we may have of a service. It is a PITA when a service tries to unify all the accounts used by a single person. Notably for example, Apple, makes it difficult to separate our faces as professional developer employed in a company, amateur or free-lance developer at home, and iDevice user. And using the same computer, you may have to connect to the service using all those facets at different times! This is the reason why Google policy of using real names and unifying accounts is bad. I mean, it's good for slave owners dealing with their cattle to have a unique identifier, but it is not how humans' lifes work.
