I've talked on this blog before about the importance of beign a best-mover rather than a first mover. Speed is not the route to success... being better is (as well as many other factors). Just found this article from a new book on this very subject: Will and Vision: How Latecomers Grow to Dominate Markets

"Consider for example the following:

Gillette entered the safety razor market decades after it began but has dominated it ever- since. Microsoft dominates many markets but has pioneered none. Amazon is the dominant but not the first Internet bookseller."

Paul sends me this lovely article: Article - Information Architecture with yet another variation in our defintition.

"Information Architecture (IA) is the science of designing the labelling, navigation, organization and search systems to help people find and manage information more successfully."
