I would like to add one little tip if you’re really, really concerned with file sizes, that I saw when looking at Google’s homepage source code.

Don’t use the quotes around the HTML attributes when you can. Most browsers will parse cellpadding=4 and cellpadding=”4″ the same way.

I know that ommiting quotes is “wrong”, but then again, these little ” and ‘ probably save Google a few thousand dollars in bandwidth costs a month.

Taking the digg.com homepage for example, which has 48.013 bytes when I save to my computer, ended with 45.582 bytes after removing every quote. I know not every quote can be removed, but I bet digg owners would be very happy to save 1Kb per page in bandwidth costs. Even compressed, these files have a 300 bytes difference. *If* Alexa.com is somewhat close on its pageviews counting, which shows digg.com with 120 Million, we’re talking about major dollars here :)

But I guess that much necessity of savings are only for a few websites…
