It's getting worse
A few years ago I hand-crafted a website (that I still keep updated) with just simple displays of titles and content lists. It was a basic but presentable display. I was quite pleased it seemed to load as fast, or even faster that similar ones.
Not long ago I was chatting with a couple of guys interested in the same subject, and on showing them what I had, noticed they'd suddenly gone very quiet. It seems they were unused to being able to flick through menus so quickly.
