How Google Grows...and Grows...and Grows.... and despite the little tale of nine words/120 bytes... Google has its collective head up its arse if it thinks saving those 120 bytes makes a difference, compared with what they'd save if they created some valid XHTML instead of the tag soup they call an interface. Their design is based on tables, which are not lightweight code. Meanwhile, on their subpages and alternative homepages (eg. google.com.au) they slice up their logo into several small images; which means each browser is sending extra requests up and down the pipe and it takes a bunch of extra code in the page to render it. On top of that, they repetitively specify styles throughout the document instead of setting it once with CSS. On top of all of these points.... they don't meet basic accessibility requirements.
So, while they may want to deliver their results faster and make users happy; they can't see the wood for the trees.
They should hire me, nagdamnit! :) I'd sort it out :D
