Whatsapp relys quite heavily on FREE push notifications from google/apple.

I wonder if either of them might decide to charge a small amount per notification anytime soon ?

Find to amazing that there are people out there that think the world has come to end when WhapsApp is down for 24 hours.

I think Walking Dead is based on the aftermath of a massive EMP burst that destroys all electrical items and the Zombies are actually Teenagers who can't use their phones anymore.
