The problem is that in the past, this site wasn't so biased.
So, we've been visiting it supposing that.
Now, if it becomes biased, you might not visit it anymore. And considering how you found the site good before that, you'd probably prefer to continue visiting a good site rather than stopping to visit a bad one.
Just IMO, of course. I think GR Talking would be fine if he looked a little less nVidia biased. Being a little biased is np, but being heavily biased is not.
