If you think Gruber's biased in favor of Apple, just wait until you meet Steve Jobs.

I'm only half-joking. I mean the whole POINT of DF is that it's written from a very Apple-centric point of view. That doesn't mean lavishing uncritical praise on everything Apple does, while mindlessly heaping opprobrium on their competitors. What it DOES mean is cultivating a point-of-view that attempts to closely track the one held by Apple itself.

If Gruber says something is idiotic, what he means is "I think Apple thinks this is idiotic, and here's why."

Obviously, his insights aren't perfect. But given that Jobs & Co. don't blog, DF provides one of the more reliable guides as to what the folks in Cupertino are actually seeing and thinking. Its sustained success indicates that, all things considered, Gruber is doing a pretty solid job.
