The overwhelming majority of bits or bytes spent on scripting are (a) put there — however naively or unknowingly — by the site owner, himself, and (b) put there with the express purpose of facilitating relatively benign background tasks: the big three of which are advertising, active content service [ie: CMS] or the many flavors of SEO, including site-navigation.

Yet all of that pales in comparison with the threat now posed by maybe half the blogs I visit: loading the site’s mainpage brings you the contents of dozens or even hundreds of posts, all at once…many if not all with embedded images or flash video players. It’s bad enough to trigger such a digital landslide from a desktop, but on a mobile it’s nightmarish.

Yep, it’s out of control.

Obviously, those tools are not inherently bad, but the ability to easily add all sorts of rich media combined with a ton of extra scripts leads to some morbidly obese pages.
