people want (in ecommerce sites, news sites, actual websites, etc): working back buttons, regular scrolling, open-in-new-tab that works, elements that don't move around, obvious and not-hidden navigation, and also tons of gimmicky/flashy crap.

people want (in desktop replacement spa's where they spend hours and hours): app-appropriate usages of keyboard nav; background tasks with status windows, working back buttons that don't stop the music stream; links that work like links & app-clickables that work like buttons; refresh buttons that refresh (via a page reload) their current full state, but working.
