I'm interested in how this applies with another one of the author's posts - about the rise of Behavior Generated Content (<a href="http://blog.hellohenrik.com/?p=268" rel="nofollow">http://blog.hellohenrik.com/?p=268</a>). It seems like there should be a good idea in combining the two (and in fact, I'm working on something that does that).<p>I don't know if it's about pure shallowness or vanity as much as people simply enjoy a little attention now and again (some more than others). It relates to the Maya Angelou quote: "I've learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel." It's a great concept to start incorporating into our applications - how are we making people feel by using our applications?
