You're right. I know I'm "supposed to" for some reason, but I guess I don't have a problem with "friend requests" from people I don't know. I thought the saying was "You can't have too many friends", so I don't even know why people rail against it. It's like "likes" on YouTube. Do YouTubers or Facebookers only accept "likes" from commenters they've vetted? As for telling you about myself, I wouldn't know where to begin with such a question. As you say that takes time. In any case, I don't think a person's "wall" is the place to do it.
