I haven't read much chick lit so I can't really comment as an expert. In total I have read:
Bridget Jones Diary - : pretty good, made me laugh, but she did irritate me in a kind of "oh pull yourself together" kind of way.
The Big Love- Sarah Dunn: Funny, well written, enjoyable. Liked the central character. An easy read. The spin in this book was lots of religious as well as relationship angst which made it fairly interesting.
Karma - Holly Harvey: Funniest book I'd read in ages. Not a highly polished book and flawed in some ways but I just loved the humour in it.
The Wives of Bath - Wendy Holden: Pretty darn awful.
I'm currently reading a Freya North (Love Rules) which I almost put down on page 4 but is actually keeping my interest now.
I would class all of the above as chick lit.
I go with the traditional definition, generally relationship focused, about single women in their twenties. I've never read a book that was classed as chick lit but didn't meet that definition (at least loosely) but then I don't generally read books like that much anyway.
I'm not normally attracted to chick lit but I am attracted to light fun reads now and again. I prefer adventure in my stories to shopping, but I will no doubt read more in the genre, and judge on a book by book basis.
