Going into it, I knew the book had been published in 1999, and that HBR case studies can be 3-5 years older than their publish date, but thought I could pick up some useful information nonetheless. As expected, most of the examples were outdated, and didn't really apply to the new world of online media and advertising. However, some of the nuggets for successful branding still apply, like: keeping things simple and not clouding your brand with too many offerings, keeping focus on specific channel strategies and being consistent in our messaging, not buckling to competitive pressures around cost if it means compromising the core product/service, and of course, know your customer.
A much more interesting and useful book that I'm reading right now is "Don't Make Me Think!: A Common Sense Approach to Web Usability" by Steve Krug.
