I'm curious has to how many other developers are using HTML5 and CSS3 these days?
I couple of years ago I still had to test using IE6 and up to keep stuff backwards compatible for a few clients. But now I'm more thinking screw it, if they want to be stuck with a old browser they can upgrade for FREE then I'm not wasting my time and I'm going to make something nice and clean while using the newest techniques my browser supports.
Today I get the feeling more people are adopting smarter browsers and most (if not all) smart phones and tablets fully support HTML5 and CSS3. I have only seen 1 person in the last year that was still stuck using IE6 and she was a complete freak worried that even if her phone number got online her bank account would be drained.
I'm just curious what others are doing for clients these days.
