And finally, anyone who tells you that any of these concepts will make your web site look better on mobile devices is selling you snake oil. Older mobile devices only supported a weird fucked up subset of HTML 3.2, and newer mobile devices have ultra-smart browsers that reflow even the most rigid designs and parse even the most fucked up Tag Soup markup. Every new mobile device that comes out seems to trip up on CSS in its own way, and apparently nobody told the mobile vendors about XHTML Basic (don’t ask).

Damn right - Mobile web browsers are screwed-up.
