Wow, your time is obviously a lot more precious than mine! I find that even things I disagree with or find 'shallow' are great for getting me thinking. I found the debate itself about fundamental under-the-hood changes versus superficial but easily noticed ones very fruitful, even if the article itself wasn't perfect.
I don't mind reading things I disagree with. But it's a waste of time reading opinions that a trivial amount of thought reveals are obviously simplistic if not downright wrong.
Just because I avoid this particular blog doesn't mean I don't get thought-provoking discussion elsewhere. We all filter what we read. Repeated posts that are mostly trollish traffic generators, prodding me into time wasting discussions of no value (http://xkcd.com/386/), have convinced me to filter this one.
