There's gonna be a point in the future that people are gonna have to click 10 ads to see 1 friend update.
And they'll be okay with it, just like people love The Super Bowl ads. I can see how people will say "What I like Facebook for is the ads!". They don't have to steal your credit card to make you buy stuff you'll do cause you like the ads!
Litecoin actually did last night, more volume than Bitcoin, the fees were almost nothing! I actually did send an LTC transaction last night, so much fun not to be stupid and take advantage of this revolution instead of just sitting around like a troll calling it a bubble :D
Try Steem (almost Steam lol), it's meant to do that https://steemit.com their site is a social network where people get pay on Steem that isn't trying to phish for your personal data.
Why overcomplicate things? :)
Oh yeah cause of culture, the same reason people like gold or people like diamonds or bitcoin.
