Even though I would normally want Marc in my friends list in Orkut, I decided today that I had to remove him. Currently it seems that he has just added everyone he can to his friends list, and it seems that introduces a lot of friend-spam... I may have to re-think this, but it seems that social computing breaks down when the "friend" relationship doesn't have meaning... For example, today I declined some people because they weren't really my friends (I had never heard of them in fact)...

How should this work?  Is it purely a networking device (in which case we are all each others friends) or is there supposed to be some relationship present to justify the link? Should their be a quality of the link ("just met", "good friend", "best friend")?
