I agree. Facebook is awesome for keeping in touch with people that I normally wouldn't keep in touch with (people who aren't close friends but are still friends). I've made great friends through it and my news feed always has relevant content. The experience is what you make it. If the OP lost touch with people it's because he made no effort to keep in touch with them.
Not to mention the obvious click-bait of his submission... "goodbye facebook"? Please. 900M accounts. They're not going anywhere for some time.
