Here’s the thing- I hang with these people, talk with them, and to an extent know what they know. These books are not written for me.
So why even buy them? Two reasons I can see:
1- Friends support each other. That should need no further explanation.
2- Give your copy to someone who will benefit from it (if it’s signed, lend it or buy a second ;)).
Ok, now that I’ve said that, I had better do it too, right?
By the way- a good example of the same kind of thinking is Christopher Penn’s review of Trust Agents by Chris Brogan and Julien Smith, both of whom he knows well. Have a look: http://bit.ly/HEcC6
