Remember ChaCha.com? They created a lot of buzz in September of last year when they officially announced their human-powered search engine. I had blogged about it and after doing so, received a flood of inquiries from people who wanted to work for us, thinking we were ChaCha itself. Not only did I find this amusing, I had also voiced my opinion that their concept may have been useful before we had search engines that can retrieve results in nano seconds. But why now?
