I don't think I've ever seen Norb knock a bow in the ground but if you read his reviews he does stay pretty objective I think.
The vast majority of the bowhunting world aren't tech freaks like we are (though I belive there are more than ever) and a serious "Con" in your and my eyes the average Joe Bohunter will never notice and that's who he needs to target to sell magazines.
That being said...
I've always wanted to meet him and got the chance at the ATA show in Jan. He was at the Wheeler booth talking to Mark when I was there and long story short....his personal opinions and what he writes are GREATLY affected by the sponsors for certain magazines. I asked him some very specific questions on what he though of certain cam designs, riser materials and such and I got a sly smile and "I'm not at liberty to comment" retort....'Nuff said?
