Mark Zuckerberg  is acting on his promise of putting Facebook's mobile services  first--after all, mobile is where the action is . Last week we had the Poke app , Facebook's Snapchat clone, and as of yesterday, users of Facebook's iOS and Android Messenger apps can now leave voice messages for friends .
And if you're in Canada, you can make and receive VoIP  calls. Expect this one to be a runaway success and, when it almost certainly rolls out to the rest of the world, Facebook will be providing free phone calls to a billion people--unless, of course, its plan is eventually to charge for all the extra little doo-dahs that other VoIP providers charge for.
