With all the choices in web browser technology, it’s foolish that some designers feel compelled to create web pages that are “optimized” for a particular browser and display settings. There are two reasons that I can think of that they do this. One, they believe that most of the people who browse the World Wide Web have, by now, similar systems and use the popular browsers. Second, they feel no need to try and set up a site that can be viewed by anyone, i.e., they’re lazy. By doing this, what they are essentially telling me is: conform or die.
People use the software they use either because of system limitations or personal preference, so if you want them to visit your site then you should find a way to cater to them, and not the opposite. A platform independent, non-browser specific Internet site will give an advantage to those companies and individuals that take this course and avoid the easy “solution” to this issue.
