I don't even think that the reason is "Facebook isn't cool anymore". Facebook is just annoying at this point. When Facebook was for your friends from college and/or high school, things were great. You could post embarrassing things that people did, inside jokes, whatever. Now your mom is on Facebook. your grandma is on Facebook, and so is your boss. Yes you can stop them from seeing everything you post or everything your friends post, but no one knows that. There's probably a 50/50 chance that if I were to post something funny and slightly embarrassing on a friends wall, BAM, there's their grandma who is a tad bit confused. Then of course your friends grow up and all they post is baby pictures. Teenagers, who are looking to keep things private between them and their friends, can't have their mom popping up on their Facebook pages all the time.
