Two companies that you don't hear much about these days have partnered to help improve online Q&A. ChaCha and Wolfram Alpha have now combined forces to improve the quality and depth of answers to online questions.

We wrote about ChaCha many years ago and Wolfram more recently last January about their APIs. Both companies had big splashes when they introduced their technologies.

In the partnership's first day, Alpha answered 32,000 of ChaCha's incoming questions, according to ChaCha. Given that ChaCha is used by millions each month, that isn't all that impressive, but there is opportunity for growth, and maybe a goal to make the Internet a more accurate place in this sector. Alpha can answer the most arcane factual questions, such as solve mathematical equations or delve into scientific knowledge.
