I have been thinking more and more about using iMessage with my email address versus my phone number. John Siracusa on the Accidental Tech Podcast made the case for it a while ago that basically communications are moving away from IDs tied to things like phone numbers and more to email addresses. I can't exactly recall the rest of the conversation but it got me thinking. I like my phone number. I don't want everybody I message to know my email as well necessarily. Anybody have a compelling reason to switch to email address?
