It's always fun to get a snapshot of where we (people in general) are in developing etiquette or, as Macworld put it, "social graces" on the social Web. And that's all there is, really, in this little article, a little snapshot of where the thinking is. The best reminder in it, for teens (or anyone) concerned about being seen as mean or snobby when they're just protecting their own interests or privacy in Facebook, is that it's ok to delete someone from their friends list – Facebook doesn't make an announcement or anything. Also, there's a good answer to the question, "What do you do if you get an unwanted invitation?" "I say ignore invitations without shame. Some people send them to everyone they have the slightest connection to – in that case, they probably won’t even notice your silent rejection."
