He (staunch) is not 'scared of the new ideas' - quite the contrary, he says they're pretty standard for anyone with a clue.
Perhaps the point of this book, if you read all the way down, where he talks about why he went the traditional publishing route, is that it's to spread his message to people outside sites like this, to people who are not so attuned to the latest goings on in the world of startups.
Which, paradoxically, might mean that it's not a good buy for most of us in that perhaps he's just repeating stuff we've already read?
