What's in a name?
The wrong name can ruin a character for me. Whether it's a name I associate with someone else or simply a name that doesn't fit the character in question, seeing it used over and over can (and will) take me out of the story. Obviously, all the authors in all the world can't dip into my head and use names that don't have any negative connotations for me - although my head is very fun and all the authors should want to get all up in there - so it's something I have to deal with. Or I have to walk away from the book.
So... Have you ever decided against reading a book because the name of a character reminded you of someone you hated? Or have you ever started a book and thought "Oh, this person does not fit this name!"?
