For me, Charlie is a fun novelty, and I often find his posts rather amusing. I don't care about his bias or "hate" simply because I'm an individual well capable of thinking and drawing conclusions so I treat his way of criticizing nVidia ("Dear Leader", "habitual values", etc.) as a flavor that makes reading quite fun sometimes, although it's not always appropriate and often exaggerated.
As for credibility, well, he's semi-accurate, and the site name fits. I take everything he writes with a grain of salt since he's been wrong quite a few times. However, his Fermi info, while exaggerated, proves that he IS indeed well informed and certainly has an inside source @ nV.
No question that I'm going to continue reading his "nonsesne" - it's often at least partially correct, and it's fun, too, even if his style is slowly getting old.
