Since this is the third addition, could you please point us at some reviews for the first two additions? $3 is a no brainer and you should probably charge more, but the cost of time invested in reading is what is valuable. One question I have for authors is "What book would you recommend over your own book?" I ask this because I once met an author of many technical books going back 20+ years, but I was supremely disappointed when I discovered that he wasn't familiar with some of the most highly regarded books in computing like The Little Schemer, K&R, etc. It's clear from your books, that you're not clueless like he was, but I'd still love to hear what books you look up to as an author.
