I'm still as confused as Ian here. This isn't a default value. You use
@value for that. @placeholder can represent a *sample* value, but that is
*not* intended to be submitted, and has no need to be editted. It's never
expected to be directly useful, but rather just to show the user directly
what is expected in the field.

Actually, due to the prevalance of this sort of thing, most people are
rather used to gray (and possible italicized) text in an input disappearing
when they click into it. It doesn't confuse them at all.
The fact that it *is* relatively widely used, and isn't confusing to the
average person, means that the suggested presentation *is* useful.

Actually, it's really not any great length at all. For example,
http://www.kryogenix.org/code/browser/labelify/ is a dead-simple jQuery
plugin that does it automagically for you. There are several other variants
on the theme (this is just the first I found in a quick search), and I'm
certain other js libraries have similar things built for them.
The problem, of course, is that alternative display devices which try to run
differently may get an extremely messed up result out of any js-based
solution. By building it directly into the language the UA can decide
precisely how it wants to render and control this sort of thing to be
maximally useful to its users.

This is true, at least for the standard desktop browsers. They'll all
standardize on the standard gray text that's already in use, because that's
what users are used to and expect.
I still greatly prefer a CSS-based solution over this, but I can live with
