Twitter as Attention Machine

I am reading On the Origin of Stories, a new book by Brian Boyd, which to make a long story short, draws conclusions from recent research into the mind and evolutionary psychology, that status is essentially attention (or at the very least attention is the currency of status). I can see how this applies to Twitter. The ability to 'favorite' another twitter's content is yet another way of bestowing attention. Twitter is an attention machine. When visiting a twitter's profile, being mentioned or retweeted in the stream of updates or being favorited are ways of gaining attention. A twitterer gains when a user with high attention favorites one of their tweets and more so, when they retweet.
