Facebook has some uses, but people can't expect it to be everything. They can't expect it to be more than it is. For me, Facebook is good at keeping in touch with friends who are far away. They may have moved to a different place, or they may be in a vacation somewhere. They post pics and impressions about a place. I also like the occasional article links people post. Sometimes people go to events and they advertise it on FB and that's how I find out about them. I might decide to join. All these are very good use-cases. I don't use FB to share very personal or deep things, because it's not a suitable medium for that. Real life conversations, in person or over the phone, are much better suited for that. So, FB is a tool, it has its uses. To call it failure is like saying the phone has failed and we shouldn't use it anymore, just because the Internet is here.
