What would Google do?

When mulling over improvements to TRIP I frequently find myself asking 'In this situation, what would Google do?'. As part of the debate we're having it dawned on me that we could do far worse than to look at what the mainstream search engines do to demonstrate their worth.

Two blog posts should be of interest (the first links to the second):

1. Yahoo Makes Big Customer Satisfaction Gains In Search
2. Search Engines: Intense Competition Drives Better User Experiences

One other point, we had Paul Glasziou and his team evaluate TRIP and this paper is available via PubMedCentral (click here).
