Alan Lepofsky had a post where he played with Maslow's Hierarchy of Needs to come up with a Hierarchy of Tweets.
He goes on to describe each of the levels in the hierarchy as it pertains to tweeters. Very humorous.
I think my favorite is Love/Belonging. He mentions about the ego boosting banter that goes on because the tweeter think his family and friends are following him, but are not.
Nice and creative, Alan.
