IMO Yahoo! search is fine for simple searches, and they have good spider that crawls the web.The problem with Yahoo! is that they don't know how to put ads.They insert ads into my e-mails that I am sending to some other person.But look at Google they have done it wisely without interfering into usability.Another thing to note is that Yahoo!'s is ad sense clone (I think it is called Publisher network.not sure) is not widespread.I think it is still in Beta so when it becomes more widespread, The story will be different.Yahoo! Answers was one of the best Yahoo! services I like.
