Facebook may have started out as a social network that was aimed at allowing lost connections to reacquaint themselves with one another, but as we can all tell now, it's grown exponentially since then into the Internet behemoth we know today. Facebook also likes to boast that part of the astronomical social experience centered around the fact that businesses on Facebook and end-users have together exchanged more than one billion messages between them, which perfectly paves the way for the introduction of Facebook's new chat bots, officially called as "Bots for Messenger", as announced during the company's annual F8 developer conference today.
