When software is your bread and butter I think it highly unlikely you will retain your current sentiment.When I say "user," it could be your family (who should be the easiest to teach since you're a professional web designer) and, of course, those who view the website.
Ah, I thought so. However, I don't think it's much of a burden as implied. It does create consistency in design and across-the-board compatability is no bad thing.Most of the world's leading nations passed something similar I bet. In my country we have the Americans with Disabilities Act, which took effect in 1992. It covers many of the same things.
