#1 annoyance with web pages: when they tell me detailed instructions about how to go to another part of the site. "In the box to upper-right, click the Save Now link."
If I wanted to interact with information in this manner, I'd be using a book with carefully indexed pages. No, this is the web, and we have this newfangled technology called hypermedia that allows you to seamlessly link from ANY place to ANY other place.
Maybe if knowing the "canonical" place for that link helps me, tell me where it can be found, but also make it so I can just click the repeated link text to which you're directing me. Don't make me break out the browser's search function just to see where this link you're telling me about can be found.
[Update: Apparently I'm even in the small subset of people who know how to search a page.]
