CrowdFlower is a company that allows companies to outsource their repetitive tasks such as data verification and filtering. I think initially this can be very useful for internet companies that need to have content verification and data check services. Usually, it is not cheap to hire people to do this kind of job and the error rate is quite high for this type of repetitive task. I think the value proposition is to offer this type of service where companies do not have to hire people and have higher quality of service. It is a promising service.

The company received an additional of $5 million funding as stated from http://bits.blogs.nytimes.com/2010/01/20/crowdflower-raises-five-million-to-boost-crowdsourcing/.
