What do you think why facebook users are decreasing and whatsapp users are increasing?

[Smit]

I think facebook takes much load on phone and whatsapp is lite to use. So people prefer to use whatsapp insted of facebook.
Whats your opinion guys?
Also share your opinion about facebook's increasing features on whatsapp like facebook is going to add voice calling on whatsapp.

i think whatsapp is much more relaible and easier than facebook so whatsapp users are increasing and facebook users are decreasing. As we know that facebook owner and whatsapp owner is same now and i expect it also would be the reason behind it.
