Cha Cha

I just read about a new service called ChaCha. You can send it a question by text message to a network of people and get an answer. Their website (http://www.chacha.com/) says it uses technology to send the question to the most knowledgeable person on that subject. People can volunteer to be a "guide" on the website, after passing a series of tests.

The article was discussing it in the context of students cheating on tests using their cell phones. But I thought it was also interesting as a librarian who answers questions!
