William Wynn writes "Once again chatterbots from around the world are coming together to face off in the ultimate bot competition. The 2006 Chatterbox Challenge lays host to 65 artificially intelligent programs attempting to imitate human conversation. Public voting takes place from April 1 to April 30 after which the private judging will have been finished and medals and cash prizes will be given out. Medals are awarded for "Most Popular Bot," "Best Learning Bot" and "Best New Bot" as well as $1,800 to be split among the top three bots overall. Anyone can talk to the competing chatbots through the competition website."
