The real interesting statistic is page load times. If load time is remaining static whilst page sizes are increasing (mostly due to images it seems), then there isn't anything to worry about. Businesses are just keeping their websites within a certain performance envelope and are responding to greater bandwidth as it comes about. (Not to mention JS speed increases)
If on the other hand, websites are growing fatter and page load is getting slower, then there is something counter-intuitive happening. But I doubt it.
I was surprised to see that at least as far as the HTML is concerned, there hasn't been much change in the past 15 years.

There is some interesting info in the article, but the headline isn't it.
Never knew this thing existed, but seems like a really nice resource.
