We present the Alyssa QA system which participated in the TAC 2008 Question Answering Track. The system consists of two parallel streams: the blogger stream which is used in order to deal with questions which ask for lists of blog authors, and the main stream which processes other opinion questions. We also use a named entity detection component specialized to the entertainment domain. Evaluation results show that our system exhibits systematically better performance on blogger questions than on other rigid questions.
