Some Questions About Reading Habits

So I have questions for those who care to answer. I am curious about this.

1) If you read a book by an author for the first time and do not care for it, will you try a second book?

2) If you have read two books by an author you did not like, would you continue to try more by this author or will you give up at last? Does it matter if it is an author that everyone else raves about but you just don't get the appeal? Is that what would make you try more than one, two or three books by the author?

3) If you read a book by an author and absolutely loved that book but everything else you have read by that author has been mediocre, would you continue to buy that author's books in the hope you'll find another book you love or would you eventually give up thinking the first one was a fluke?

This is just pure curiosity on my part because of some of my own observations on reader sites and blogs. So this is just for fun if you care to answer.
