Ensure continuity for the customer is one important principle. It means that you have to follow your customer needs. You do not have to use new technologies on your website just to be modern : you have to pay attention to customers practices.
For example, Web TV networks try to connect home television with the phone network because some people don't want to have computer to be connected on Internet. It's a service to a market that wanted Internet without having commputer.
