As a reader...
... I like a character's name to either be "fitting" (it suits the character somehow) or deliberately ill-fitting (for example, an ugly person named Beauty).
... I don't like characters with similar names (for example, Henry and Harry).
Fellow Readers:
Do the names of the characters in books matter to you?
Do you have any pet peeves about the way authors name characters?
Should a character's name somehow reflect or relate to his or her personality or purpose in the book?

As a writer...
... I use a lot of different sources for names, and I do try to choose "suitable" names.
