Therefore, I'm sad to admit that, in this case, he almost has a point. The use of attr('height') to mean not the height attribute in the DOM but as an alias for height() smells wrong to me. However, it's clear that he has absolutely no intention of becoming a productive contributor to jQuery or helping in any way.
By contrast, let's take a minute to appreciate this Matt Kruse fellow. He has apparently strong objections to something in jQuery's design and is taking it to John Resig. He seems ready to engage in a real dialogue. The end result? He probably ends up a little happier and jQuery ends up a little better.
The real question is: how can we have more Matt Kruses and fewer David Marks in the world? Do the David Marks of world drive off the Matt Kruses? (I think they almost certainly do.) Why are there so many sociopathic personalities in circles such as this, and how do we mitigate the damage they cause?
