The top-voted comments here are a great example of why people are agreeing with John Gruber's assessment of comments.
What makes DF an efficient and effective soapbox is exactly that it is not noisy. My goal is for not a single wasted word to appear anywhere on any page of the site.
Those comments distract from the article with fiery, irrelevant rants that show the authors didn't even RTFA. The whole point of the article is lost if you start reading them.
