What are you saying? That non-power-users like and are good at deciphering different designs and interaction models and layouts for every site, but they can't deal with regular, plain, bland sites because those are scary and confusing?
If anything, shouldn't that be the other way around? Power users wanting javascript experiments, and non-power-users wanting "if it ain't broke, stop messing around with it"?
No, not scary and confusing. Users (meaning non-power-users, generally) aren't always stupid. (In fact, given how well they can break our stuff, I'd say they're often smarter. But I digress...)
What I'm saying is while we might be comfortable looking at plain HTML with #000 text on a #FFF background, a user isn't going to enjoy it very much.
While we might use ctrl+f to hop around a page, a user will probably prefer a search bar with instant results that doesn't cause them to lose their place on the page.
Consider: my mother (not picking on her!) definitely notices when websites run slowly. She hates it. (I got my lack of patience from her :-) However, I'm confident she would trade "slightly slow" Facebook for "have to refresh the page after each action" Facebook.
