Well, actually, a better title would be "Why you should invite Yehuda Katz to your user group meeting." A user group meeting is the perfect place for lively conversation and free, unfiltered exchanges of ideas.

Even without knowing any of the context that prompted Yehuda to intervene so forcefully, there's a strong probability, based on his remarkably proficient community involvement, that he was making a good point. Would remaining quiet and letting the speaker present his code to a much larger audience at a conference be better?

What's more important? People feeling good about themselves, or people learning? Not that those options are mutually exclusive, but it makes no sense to sacrifice the latter for the sake of the former.
