I think the author may be making a hasty generalization but I agree with the sentiment that many web designers are self congratulating blowhards. I can't tell you how many times I've heard some self described "creative" wax endlessly about color palettes, their feelings or design in general. The result is often a Photoshop file they can't implement so the file makes its way to a "coder" or if they're being generous a "developer." The tragedy for the developer, apart from being the lowest in the chain of command and first to be laid-off, is that he may be better at design than the Designer. Just because someone calls themselves a designer doesn't mean they are better at design than someone who calls themselves a developer or hacker. If you are good in Firebug's HTML tab and you care about every pixel, IMHO you are just as deserving to be called a designer as someone whose sole output is Photoshop files.
