Facebook announces new messaging service
As predicted Facebook did announce what founder Mark Zuckerberg called a "modern messaging system" (catchy name) and although it will be possible to have an @facebook.com email address it really isn't intended to be an email system. The system is designed to combine email, sms, facebook messages and chats into threads. The goal, they say, is to have continuous, threaded conversations with your friends using all forms of messaging. So no need to type BRB or AFK when you step away from your computer because the same conversation will continue, seamlessly, on your mobile device.
A "Social Inbox" will keep everything organized, prioritizing messages from your closest friends and sending the rest to the bottom of the pile. So for now at least, Gmail and other email systems can keep calm and carry on.
This does seem like a step in the direction of messaging dominance by Facebook, however, putting it closer to being the one-stop shop where we communicate with our friends and contacts.
