John Battelle reports that A9 CEO Udi Manber is leaving the company to join... yes, wait for it... Google.
A9 is an Amazon-owned company offering web search. When A9 launched, I was expecting them to go after personalized search, but they instead pursued a form of distributed metasearch, combining search results from many search engines on to one page.
A9 does have some clever and unusual features, including A9 Maps, which can show you pictures of the storefronts on each side of a street for some locations and some cities.
Amazon offers discounts at Amazon.com for using A9, but, despite giving away free money, traffic growth on A9.com has been weak since launch.
Update: Fourteen months later, Udi Manber is now a VP at Google "responsible for core search" while A9 suffers an 80%+ drop in traffic.
