I guess I was thinking of college students when it comes to teaching. The reference librarians all do course bibliographic instruction & it includes search strategies. The most important strategies possibly being clarifying the question & then to figure out the most appropriate tool for the task (the reason your site is so good) Since it's course related the students only get it if the prof requests it. The students are also really good at ignoring advice on how to narrow a search & instead print out hundreds of citations.

The web really is new & a new search engine comes along almost daily. It's really hard for the curriculum guides & such to keep up. Without good internet connetions it's hard for the teachers & librarians themselves to get up to speed.
