This should be a wake up call. This site really doesn't deliver anything of value. It doesn't really make you more social and it doesn't really connect you to people in the real world. So basically you spend 16,800 minutes a year on Facebook. That is 11 days of your life lost a year.
I get value from Facebook just like I get value from Hacker News, Reddit, Messenger, etc.
It literally helps me connect to people in the real world - I just discovered Tycho's new album through there, planned a trip to a festival with friends there, just filled up my weekend, and discovered a new area I'm going to go rock climbing.
If you are getting no value from Facebook, you're probably not using it correctly - which you can change.
Hacker News is for me a news and discussion portal. Reddit is something that might show up from a Google search. I block most of the distracting internet during the day - except FB and HN - so of course those two get the majority of my allocated distracted time. I should measure it, but I'd not be at all surprised if they each got an hour a day.
