That being said, it makes me uncomfortable that an article called "Why you shouldn't invite Yehuda Katz to your user group meeting" near the top of HN, especially because he seems to have become a bit of a punching bag lately (see Rails.app). I really wish we as a community spent less time dragging people down, especially ones who contribute so much great code.
This shouldn't be about Yehuda. This should be about all of us being nicer and better people. It's sad to see an opportunity for discussion be used to bring down one person.
