No "About Me" - No Interest - No friend - No message

My biggest annoyance on SW is the person who complains of being lonely or not getting any responses or friends on the site, but posts no information about him/her that gives me a reason to want them as a friend, or message them or be interested in them. I want to know something about people, at least enough to give me a reason to "friend" them or talk to them. Otherwise, what is the point of being on here?
