Seemed obvious to lots of people who live in reality. There's definitely a weird echo chamber on HN that decries FB along the lines of "Oh no one I know uses it, therefore why does it exist", meanwhile 2bil+ people are using FB apps every day. Always makes me laugh when I see those ridiculous statements - there's even one in the comments here!
