ChaCha has added another $7 million in funding upon the completion of an E round on Dec. 22. ChaCha, which has now raised some $52 million since its inception 4 years ago, is an "answers service." Users can submit questions via text, phone call, the company's website, or on Twitter, and receive answers for free in minutes.
In the third quarter of 2009, ChaCha passed Google in mobile text traffic. When ChaCha's mobile service launched in January 2008, Google had nearly all of the mobile text search market.
