I just want to point out the logic of this, for those who think its "petty". My employer (who announced earnings yesterday and immediately plummetted into the stock toilet) serves up, oh, several hundred million pages views a day, or some such nonsense... if you look at the front page of almost every one of our sites, you'll see much the same thing the poster is describing ... they're optimized to reduce the number of bytes to what is absolutely required.
This is good for your users... it takes less time to download.
This is good for your site... less bandwidth means cheaper costs and better performance of the server itself.
It's win-win all around.
