Now that a week has passed since Facebook bought WhatsApp for $18 billion, it's time for our obligatory post about it.

Just to get it out of the way, I have no clue why Facebook bought WhatsApp for this amount. My guess is that Facebook's social network is dying (especially among teens) but its ad platform is revolutionary. Buying WhatsApp and its 450 million global users enables Facebook to remain on top for mobile and ads, though given WhatsApp owns no real data on its users, that's in theory. Mark Zuckerberg is far smarter and more successful than I, so I'll give him the benefit of the doubt.

What does WhatsApp have to do with games? Absolutely nothing. But, messaging and chat could be the next big thing in games, Facebook and WhatsApp notwithstanding.

WhatsApp really has nothing to do with games. Just look at the famous handwritten note between WhatsApp founders.
