I would say, outside of maybe the ability to write prose longer and more polished, I am hard pressed to see game journalists being more competent and professional than a number of better posters on here. Can anyone fill me in exactly what they do differently that has them doing what they do for a living compared to people who post on here for free? In more extreme cases of them, they get WAY out there, like the way people do on here.
This point is coming to my mind when I see the latest N4G stuff on this site now as news feeds. It is ranking right up there with some of the more notable trollish posts I have seen people put on here.
