You won't find me disagreeing.  ^_^  Indeed, I love being able to just
put text in my own markup, add a fancy background and some
positioning, and create something which is simultaneously trivial to
edit, pretty, and accessible.  But when you have some really
fancy-pants text compositing with your logo image, you can't go far
wrong with just creating an image for it.  I think the "content"
property is the way to go here in the long run, but for now I just
like reminding people that fancy techniques are often less necessary
than one might think.

Of course, if one wants to have a hover effect in the picture, then
you're a bit screwed.  You'll have to use a text-replacement technique
for that, or javascript.  I'm still not certain which I like better.
I'll be happier, though, when I can just do:

<h1 #logo>Welcome to BigCorp!</h1>
#logo {
  content: url( "header.png" ), contents;

#logo:hover {
  content: url( "header-hover.png" ), url( "header.png" ), contents;
