If PG has something worthwhile to say, it is true whether he has a vested interested in the truth or not. If it is false, it can be debunked without questioning his motives.

Here is what I have observed about people. In general, people with vested interests do not lie. What they do is pick and choose the truths they want to share.

So someone with an investment in an online photo editor might say that "people are now writing online photo editing applications," but is unlikely to say, "that are faster and have more features than Photoshop."

Is that bad? Of course not. There are this other group of people with no alleged interest in the subject. They are called journalists. And you know what? My observation is that they are much less reliable than peopel with a "vested interest."
