She's based on AIML/Alice with a combination of brainfiles from all over the place. She talks to random people to bootstrap conversations from the global twitter feed, then carries on conversations as long as they @reply back and forth. She's not perfect, and sometimes things don't make sense when truncated, but she manages to live on.<p>It's interesting to see actual people arguing, conversing, and flirting with her... thinking she's a human.
