For anyone who questions the importance of search engine optimization, and for anyone who wants a great read on how business is evolving, read Kevin Kelly's "Better Than Free." The search junkie in me loves this brief excerpt:
No matter what its price, a work has no value unless it is seen; unfound masterpieces are worthless. When there are millions of books, millions of songs, millions of films, millions of applications, millions of everything requesting our attention -- and most of it free -- being found is valuable.
Thanks to colleague Jesse Shaver for the link.
