Yeah that's one way of looking at it and I once did so myself. I've seen various projects of Kim Schmitz (aka Dotcom, aka Kimble) since the late 90s and all of them ended up failing because they weren't sustainable in one way or another. But he always came back with something fresh... This time he is trying the same things twice. So my personal opinion: lame.

The issue here isn't that you need to do something better to critique what someone else has done. You don't need to write a book to have an opinion on a book.

The issue is that it adds nothing useful to the discussion.
