Woohoo! Get ready to rumble...
Ya, it will. That element has been deprecated for quite some time.
Heh! It's that type of thinking that has gotten us to where we are today.
Survey? Did they scan the entire Internet and then crunch the numbers from there? Or was this a select group, not unlike yourself, who participated in the survey? ;)
It is actually the other way around. Browsers are developed around the standards. And then the developers have to take into consideration all the things that are non-standard. It is a real pain in the arse, I know, I've spent the last few years building a tool that emulates the browser and bot. Freakin' HTML errors are a time suck in providing accommodations. :)
Not a valid argument. It pains me to see the largest Internet brand not take this validation thing seriously. That doesn't mean you or I don't have too.
Of course it has. Do you know the process involved before that book goes to press? Man, that thing has been "validated" by numerous people. And if it hasn't, you're going to end up with poor grammar, typos, etc.
And last but not least, let me address this comment sir...
That would happen to be every site under my control. Juvenile? Oh boy! I'm going to chalk that comment up to jealousy. I hear it all the time. It usually comes from those who can't get their pages to validate no matter what they do. Don't worry though, I'm here to help. :)
