"A designer that can design for any framework with standard CSS/HTML is more flexible than a designer that knows HAML, but could't write vanilla markup."

This is a very bizarre statment. How can someone write haml without understanding HTML and CSS? How could that even be possible? Haml is little more than classes, ids and element names.

In my experience as a Ruby contractor I've seem many, many more WTFs in erb than haml, to the point where when I join a project using erb I now brace myself.
