Vertical Search for B2B

VerticalSearch.com has launched as a business-to-business search service covering health, transportation, agriculture, construction, telecommunications and other industries, drawing results from from over one hundred B2B verticals. The site is in beta, and offers only a basic search with no refinement or advanced search tools, so results vary widely in quality depending on what you're looking for. But probably a site worth keeping an eye on if you do a lot of B2B type searching.
