This is true beyond software. It used to be that the proof of the thinking process was in the resulting artifact. No longer can you estimate from the existence of a piece of text and the level of polish behind it that the apparent author has put at least a reasonable amount of thought into it. This applies to comments, blogs, emails, and most troublingly I've seen this happen at my job with things like requirement specs. Now, the veneer of quality makes it much harder to know what is the appropriate amount of skepticism to judge the contents with. And it's too tiring to be maximally skeptical about everything.
