My colleague, Jillaine Smith invited me to check out this cool new search engine, Eurekster. I It is powered by social networking technologies. Eurekster continuously "learns" from the behavior of users and their social networks to deliver personalized search results and instant sharing of their popular Web destinations and searches. The service allows users to confidentially and privately share their knowledge and experiences with each other, simply by using Eurekster to search the Web and navigate to sites of their choosing. I've yet to download the toolbar because of some privacy issues. I haven't figured out how to distinguish between personal and professional searches.
