Here's are similar comparisons between my book and Mark's as documented by Eric Wilson both on his blog as well as in an Amazon review... see http://amazon.com/review/RKG44D8GQYLNL and http://wilsonericn.wordpress.com/2011/09/26 for details. So yes, some people don't like it, but to others, it's just what they needed.
@ashconnor: that's another valid type of reading list. in this one, i think i compiled 3 discrete lists instead of your more progressive idea, which is a good one. i'd like to see what's in your list. as far as the overlap is concerned, yes, you're right about that as far as the material goes, however the delivery is different and suited to a variety of reader types.
also to fight vendor lock-in, Python developers can create Django apps then run them on App Engine using django-nonrel or on any traditional hosted stack supporting Django; or move between then w/minor (settings.py) changes; don't forget data migration as well.
