Yeah I would not call the stuff he says "credible". It's not just the "delivery", he spouts off things that are just plain wrong, and never acknowledges or apologizes for it. The message is bad too.Overall I like Andrew however he has a bad habit of speaking before truly researching stuff.
I don't care if he's a nerd, or if he's abrasive in the way he talks. I am a nerd and I am abrasive when I talk. He just says stuff that's not true because he's being a crybaby about Land Rover taking his toys away after he said something that was not true.
