I'm talking about these.
Yeah, I know they are intended to show that the page conforms to the standards and should link to page revalidation service. Ok. But why should I as a regular user bother with this? As a visitor I'm indifferent to whether the page is strict XHTML or not, whether it contains dirty IE hacks or not. It is important that a page renders correctly, is convenient and works fast. That's all! And in reality, in many cases these requirements don't get along with W3C standards smoothly.
So what is the mania to add something targeted toward developers to a product face? Am I missing a point?
