Will Zuck’s arrogance ever see an end? Facebook claims that their new messaging system will render e-mails and phone numbers obsolete. How are they planning to achieve this exactly? I don’t know. Maybe someday phone numbers or e-mails as we know it will become useless. But it surely won’t be because of Facebook. Not that over 90% of phone user in the world are not Facebook users. Or that the Facebook account itself relies on one having an external e-mail address to begin with.
