A well seasoned pan will go beyond simply making the pan non-stick. It will impart flavour to the food in what the Chinese call 'wok hey', or 'breath of wok'.

This one is mine. And all that. Working with this definition of flavour as a Patina -- which is imparted over time -- got me thinking about digital products. The problem with digital products -- our websites, applications, phone applications etc -- is they don't age the same way as some physical things.
