Google Books (merged into BR&BC thread)
Apologies if there's already a thread about this topic -- I didn't seen one, but you can never be sure.
I've got a few books online now, through the Kindle Store and every place Smashwords can get to. Yesterday, a friend of mine asked if I was going to put my work on Google Books as well. I looked into it and it seemed simple enough, but when I made a comment about it on twitter another friend came back with the comment that "Google books isn't exactly interested in paying you for your work."
I haven't submitted yet, so I thought I'd come here to the experts. Does anybody have any experience with Google Books? Any pitfalls I should be aware of? Worth the trouble or avoid it like the plague?
