Facebook to me seems more of a place to show off rather than actually "communicating" with people. If you want to communicate with somebody, talk on the phone or email them. Photos can be sent in email.
FaceBook comes in handy in some circumstances, but as far as everyday use like it's the only way to communicate, and like it'll replace everything else? No.
As far as communicating with someone other than face to face, email, phone, private messaging systems within a site, and message boards such as this one work just fine for me.
Since Google owns Youtube, they've taken away the 'Friend' feature (besides numerous other ways it's being ruined, pretty much taking the 'You' out of Youtube and trying to turn it more into T.V and cater to the big time people and such) on there because I believe they're trying to shove their own social network, Google+, down everybody's throats. Trying to compete with Facebook. That's not what they're saying, even though it's obvious.
I will never (willingly at least) use Facebook or Google+ and that's that. Don't get me started on the privacy issues.
