UNCONFIRMED errors and comments from readers: (75) 1st paragraph; "Experience designer Nathan Shedroff..." should probably be "Experienced designer..."

This could be a fatal error..... especially if your oncologists degree is really in ontology.... (95) 3rd paragraph, 1st sentance.; When discussing Figure 6-9, a screengrab of BBC's site index page, it refers to "Sun business units" when it should probably be something like "areas of bbc.co.uk." [145] Bottom of page; Recall and precision are defined incorrectly. They are defined correctly on page 180 in figure 9-5. That same figure should replace the inaccurate definitions on page 145. [180] top of page; The definitions given for Precision Ratio and Recall Ratio, both in the text and in Figure 9-5 on p. 180 differ substantially from those given at the bottom of page 145.
