A couple of years ago I was at a bird of prey display and the guy that was handling the birds told everyone about a young owl that he'd been teaching to catch food. Nothing they did got the owl interested in actually catching anything until one day they had the owl flying around where they keep them and it flew straight into a building. Over they rushed to see if it was ok and there was this young bird, totally dazed. As they looked at it they could see something hanging out of its mouth. When they checked it they found the remains of something it had caught as it was flying. It must have been so surprised that it stopped looking where it was going and didn't see the building in time to avoid it.
Wow! Looks like I missed a bit of excitment. I never found DF3 to be that annoying, sometimes I found his comments weren't called for or overly helpful but we've had similar on the forum in the past.
Having worked in software development for far too long the route that DF3 took to prove his point was wrong. He's have been a lot better engaging with Fetch and offering them the script he used to prove his point or agreeing with them in advance the use of the script to spam his own thread. Also as DF3's job involves working with websites then there is the question of the ethics of doing something that would likely get you a serious rap over the knuckles if you did it at work.
