Can someone explain to me what all those 7500 employees are doing at twitter? Because I'm totally unimpressed by that.

Whatsapp had 55 employees when it was sold, which sounds about right. But 7.5k for just pushing some data around? GTA was developed by 1000 people, and I mean both programatically and content wise it's way more challenging.

So what are those 7500 people working on?
