Derek,

for clarifying reasons I will use a few dummy examples. Hope you enjoy.
Seasoned guys, don't take it so harsh.

HTML is a standard for writing documents that can be shared over internet.
Now, keep in mind that compatibility is a two sides matter.

First, we need applications using those standards and technologies. I mean,
we need sites written making use of those tags and interfaces. This is a web
developers duty. You can make your part here.

This isn't complicate. You implement what you need, based on what standards
allows you to. Period.

The complicate part is the another side: support from who makes browsers.
Google, Opera, Mozilla, Microsoft, Apple, Nokia... You can use new tags and
interfaces (program with javascript/dom to add cool drag and drop effects,
dynamic drawing with canvas, use localStorage... ) but not every browser can
recognize, render and display everything as you want.

Go further. Not everyone use the same machine configuration, nor the same
browser. One person would like to use IE8 upon Windows7, another person
would use IE6 upon a Windows XP, and a third would browse using Safari
Mobile on his iPhone4.

That is the major problem from universe.

Even if all people use the latest version of their preferred browser, note
that browser vendors implement the standards they judge more important
first, and let one or another feature for future releases (perhaps the
future decade).

And based on what is used/needed according to the current status of web
development, sometimes there are extensions over the current standard,
putting more things web developers and browser vendor need/want/desire.

It's a circle. The solution? Best practices and more best practices. Google
for "javascript feature detection". That's is a good point to start.
