Remember, also, that the Mobile Web is becoming increasingly important these days - and may be especially so in developing countries in the future. This means that content needs to be adapted to fit on handheld devices with smaller screens.

Again, this would ideally be achieved by styling the content, rather than writing a completely separate Web.

You should not make assumptions, when creating content, that you know what it will look like when finally displayed. These days, it may well be displayed in a number of different formats.
