Can't we just make our own? Two or three years back when not one of
major browser manufacturers was conforming to W3C standards, each invented their own flavour of HTML (the language used to describe web pages). As a result web developers had a really hard time of it as they often had to write several different versions of
same content in order to get it to display correctly on everyone's computer. Now that Microsoft and Netscape as well as
other players are making a big push towards compliance, not only is
job of
web developer made considerably easier but
users get a more coherent and integrated experience when browsing
web.
Accessibility Widespread use of standards (or even enforced use as in
Highway Code) has another important benefit that is no less important and is almost a reason on its own to conform. A well designed standard will promote access to
system to as wide an audience as possible. Consider disabled drivers - without
provision of disabled parking spaces and
standard that you shouldn't park in them unless you have an orange badge,
road system would be much less accessible to people with physical difficulties. Likewise
W3C standards all derive some input from
Web Accessibility Initiative (W3C-WAI) that ensures that all web content will be accessible by those with sight problems or motor-control difficulties. On a practical level this involves, amongst other things, providing a textual alternative to all images, ensuring that
site will work with a screen-reader (which is a program that can speak words for blind users) and is easy to navigate without
use of a mouse.

Persistence Already we are finding
problem of reading some of our older digital data difficult. Ancient, creaking mainframes with large amounts of tape storage are now all but extinct yet there still exists
need to read some of
information stored by those systems. If that system conformed to a well known standard then there is every chance that
data can be read by obtaining a copy of
standard and applying its rules to your tapes. However if
system was custom built with no standards in place at all, and
original system no longer exists then you have increased
difficulty of
problem by several orders of magnitude. The moral here is that conforming to standards not only guarantees far-reaching accessibility for your data today, but in
future as well.
As some form of W3C-WAI compliance is now a legal responsibility in
UK (see http://www.web-access.org.uk/) as well as much of
rest of
world,
need for adopting standards has never been more pressing.
