If you would like to chat to Rosette you can at TellTaleGames. If you have been following the run up to this year's competition you may be surprised at how poorly CleverBot performed given its track record. This chatbot, which searches through earlier conversations for its answers, had received a score of 59.3% in a test that took place in India in September in which humans were rated 63.3%, only 4 percentage points higher and was also featured in a video that went viral. However its developer entered a cutdown version of CleverBot into the Loebner prize selection round and it didn't get the chance to show off its prowess in the final. So we will have to wait for another year to see if it really is as good as it claims."
Depending on your bent, you may agree with Unknown Lamer that this sounds less impressive when phrased as "fooling a person ~18 percent of the time." I think that's a pretty high number, myself!
