I wondered what would become of A9 after chief Udi Manber left for Google last year. Things weren't looking good as of October, when Amazon scaled back some of A9.com's key features. On Alexa's chart, you can see a corresponding traffic drop for that time period.
These days, is the company paying any attention to its beleaguered search engine?
