To support or not?
On the other hand, web developers and web designers are seasoned computer users, which are most of the time after the latest technology — software-wise, hardware-wise, interface-wise. This breed often has several browsers for different contexts.
Ordinary people (who are not dealing with web for money) find it hard to remember browser history stack, don’t need to learn keyboard shortcuts, they don’t know the difference between Comic Sans and Cooper Black, and they don’t know the difference between Internet Explorer and Firefox.
Regular Internet users don’t need Firefox extensions, or care if rounded boxes are done with pure CSS or with background-images…
That is our job — we need to know those differences, and provide the best possible experience.
That’s why CSS people are called experts. They can do miracles, when everything else fails. Any fool can code for the latest browser, but experts take care of every browser with significant share.
