OK, found the thread. I've flown with him. He's a passionate guy, and intelligent. He writes well. He's capable of making great arguments, and some of the most off-the-wall stuff.

His trips are in open time a lot. I personally wouldn't avoid a good trip if he was on it.

He'essentially got a similar reputation as a guy like RM or the Gold Guy. I'd judge his argument on their own merit, and not give them particular credibility; nor would I dismiss him out-of-hand.
