I was just wondering whether people would pay for an ad-free Facebook? Apparently, each user is only worth ~$2 every 3 months and quite frankly I would pay $10/yr not be served ads.
I would pay for a social network that cared about my privacy and made its money through subscriptions, not through selling the information of its users. However, I strongly suspect that I'm in the minority and that most people would rather not pay a thing. Then again, that might be a good thing. I love Google+ because the only people on it, pretty much, are techies - so whilst profile updates are nowhere near as frequent as Facebook or Twitter, they're a hell of a lot more interesting, from my experience.
