It's hilarious to me how often his work contains spelling and/or grammar errors. He's a journalist for a newspaper, it's beyond what I'd find acceptable. He's not some knucklehead posting to a message board.
It was at its worst when he first got in to the "blog" world on the site. Almost EVERY single time he posted something, there was some issue with it. Eventually they started having Ron Fritz post (re-post) for him, obviously to ensure SOME amount of editing was done before it hit the screen.
I'm close to someone who used to be his boss, and the professional opinion of those around him is the same as most of ours. They ALL know he takes TREMENDOUS liberty with facts to make his points. It's a shame really. But it's what The Sun has become over the years...
