Dan Russell of Google, notes in Why is search sometimes easy and sometimes hard? Understanding serendipity and expertise in the mind of the searcher, teaching someone to use Control-F to search for text on a page, out performs 16 other changes they made to a search interface. An improvement of 12% in time-to-result measure.
Now for the sad news:
- 90% of all US internet users do NOT know how to Control-F
- 50% of all US teachers do NOT know how to Control-F
Two questions:
- Does your topic map improve time-to-result by 12% or better?
- Do your users know how to use Control-F?

PS: This is a great presentation. I have other comments on it but wanted to single this one out for your attention.
