But they use all that data to show me pictures of crappy food, kids, drunk parties and stupid FB game ads.
But that's a good thing. It sounds like you WANT to be ensconced in a political bubble. People splitting off into echo chambers is a major source of the problems we see today.
You can only get personal updates on Facebook?
What a strange thing to say.
Does it make you feel like you care about them?
Here's what I'm getting at: if you really cared about someone, you wouldn't settle for the bare minimum of passively consuming their uploaded photos and status updates.
I posit that Facebook is popular among people with scattered friends and relatives because it makes them feel like they care. However, in my opinion, truly caring about someone warrants more than just maintaining an awareness of what is going on in their lives by consuming their content on your news feed and occasionally clicking 'Like' or posting a comment.
