Mongoose have a slightly different approach to this method of fault finding, it is called a first edition.
This is of course the standard industry practice and at least Mongoose do usually do a second edition to fix the problems unless the book is (unfortunately) unpopular enough not to be worthwhile doing so. Usually their errata list is smaller than the book as well which is not always the case with some other publishers.
I'm surprised at the relative lack of mistakes found in my early reading. The biggest problems stem from ambiguity, rather than outright errors (though these are no less challenging).
I have to say, their editor did a pretty good job.
