I was mooching through some old threads, and woke this one up!
I tend to avoid 'fluffy' names, as I feel that will be reflected in the books contents. For me, I like to think that all the words in the book matter, from the story, the blurb, the dedication, and therefore also the author's name.
Neutral names that don't have an ambiguous pronunciation, or strikingly unusual names, they will be the ones I go for if I am seeking a new-to-me author from a book shelf. If an author had a name like Tinkerbelle Muchly-Snuggles however, I probably wouldn't read the book! That's what I mean by fluffy!
