ChaCha-Ching! Amazon’s Jeff Bezos Among Group Investing $6 Million in Human-Powered Search Engine

It looks like we’ll be hearing more of human-powered search engine ChaCha as they today announce they have secured $6 million in private funding. The group of investors includes…

…Bezos Expeditions, the personal investment firm of Jeff Bezos, with additional participation from Rod Canion, founding CEO of Compaq Computer, and Jack Gill, veteran Silicon Valley investor, founder of Vanguard Ventures and current partner at Maven Ventures

ChaCha launched in September 2006 and claims to have 20,000 people signed-up as user guides. They don’t reveal how many people are actually using the search engine, but claim they have “already garnered user traffic at levels that exceed many first generation search engines”. Anyone care to guess what that number would be?
