Friends

Have you noticed that some on social networking sites, such as facebook, have more friends than anyone could really have? I imagine there are some that have hundreds of friends, or thousands. I know on my site it shows a much lower number. Maybe I need more, do you think? Or maybe some people try to accumulate more friends than they need. That isn't really a good way of putting it. I mean to say that some may try to become 'friends' with others just so they have high numbers even though they aren't really friends. Does that make sense?
