I worked with BradM for about a year or so (could be wrong on the exact timeframe), he's a smart guy who works hard and gets things done.
Unfortunately he has developed a 'board persona' of an asshole/attention getter/etc. That's just how some people choose to use GFY, I know there are many others on this board who do it the same way - it's one way to make sure you are known.
In reality he's a decent joe and, even though some of his opinions leave me a little cold I personally wouldn't have a problem doing business with him.
