It's weird that it's sort of become cool to hate on Facebook now. People talk dismissively of how they prefer "real" social interaction, implying that Facebook social interaction is somehow "less real" than texting, phone calls, or postcards, or that these things are mutually exclusive somehow.
Facebook is just a tool, like every other mode of communication. It is whatever you choose to make of it. Some things are easier to share with your friends through Facebook than through any other medium.
2014: I hate Facebook, it takes all of the interaction out of interacting with people!
2004: Look, I know you like email, but man, I want to have a real conversation on the phone! It's not like you're not carrying a phone with you all the time.
1994: A portable phone? Really, dude, can't you just use the phone at home like a normal person?
1934: I hate these telephones. If you really need to interact with someone at a long distance, can't you send a telegraph?
1894: Why should you need a telegraph? Is a written letter not fast enough or good enough for you?
BCE 2004: Have you seen this writing stuff? It's ridiculous. Kids won't be able to remember their oral history anymore with this!
BCE 54004: Word? Language? Grunt not good enough for you?
