This is a great topic of conversation, thanks for bringing to the message boards. We did some podcasts a while back on this topic, although I'm not sure we worded it as "anti-patterns".
One reservation I have on the topic could be related to a personal struggle I have with the phrase, and would like to share. Antipattern has become a buzzword in the industry the past couple years and is used more and more every day. Often, its used to describe real struggles teams have that conflict with the manifesto and principles. However, it's not always the case.
If an agilist doesn't prefer a particular practice or behavior on a team, they may describe something they personally oppose as an antipattern. And since they are the supposedly most knowledgable on the topic it's taken as gospel.
When we speak of antipatterns, my strongest desire is for us as a community to look inwards first and ask why we think something is an antipattern and challenge ourselves to see the other side. In many instances, it may be one for sure. But what if we're wrong?
Hope that makes sense. Again, I'm biased but I wanted to share for feedback.
