A suggestion for Facebook
Zachary is trying to develop an algorithm to help him choose between: status update, blog post, tweet, nobody wants to know about that.
AM: Why are you telling us this?
ZD: Because that's what Facebook status updates are for! :) I think "Why are you telling us this?" is the question that may cause Facebook and Twitter to suddenly implode.
AM: Why can we now like status updates but can't dislike them? I want to disapprove of people's status updates.
ZD: Well, you'll just have to indicate your disapproval with a comment. Still, allowing one-click approval but requiring typed-out disapproval does tilt the landscape in a "niceness" direction.
Similarly, why does Facebook allow you to have friends, but not enemies? If you had enemies, then you could click on your enemies and see a list of their enemies. Then you could test out the proverb "The enemy of my enemy is my friend" by sending those people friend requests.
AM: OMG. That idea is made of win. Please suggest to facebook immediately. Also, I disapprove of this comment.
