What's the point of this article? Sometimes it isn't about being cool, it's about being really useful to a ton of people. Driving a car isn't "hip" or "cool" (unless you're driving a Tesla) but it sure as hell eases the lives of hundreds of millions of people.
Facebook's mission isn't to be a "cool hangout" place, it's to make the world more open and connected. If they developed their product in such a way that it was only used by younger folk then they'd be excluding 75% of the population which is not connecting the world.
I'm really sick of these articles.
