As far as the softcover edition, I had offers from a few major publishers, but in the end none of them would allow me to continue to sell on leanpub at the same time. I strongly considered caving to the demands of the major publishers, but ultimately the ability to create a high quality softcover and make it available on Amazon was too tempting to pass up.
The feedback has been almost universally positive - the reviews are quite solid on goodreads (http://review.wewut.com). I believe the book provides specific, concise direction for effective Unit Testing, and I hope it helps increase the quality of the unit tests found in the wild.
