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.
Does it make you feel like you care about them?
