Yahoo! released a product today called MindSet. It offers searchers a sliding bar to re-order the results based on whether they are in an "information-seeking" stage or a "shopping/purchasing" stage. The technology is really quite phenomenal and effective. I tried several different searches and all had the expected results as I slid the bar from shopping to research.

Barry's got great coverage here and Donna's covering it well here, so this post is more of a "don't miss it" than a full explanation.

One thing I will say - if this takes off, SEOs may have to seriously re-consider how they go about getting traffic. The number 1 research spot vs. the number 1 shopping spot vs. the number 1 right-in-the-middle spot will become a very big deal.
