I’ve seen many website designs with frequent inclusions of ‘back to top’ links and am just wondering when, if ever, they can really be justified? What use cases demand a ‘back top top’ link, and what are their effects on usability?

They’re useful on long pages as long as they’re not too frequent, though over a certain size it’d probably be better to split the page up into smaller section pages. See the single-page HTML5 spec as an example why this is needed (it’s about 1MB of raw HTML).
I personally like the way Xfce’s site does it – one arrow icon in the bottom right corner that stays on screen, out of the way.
