Sierra maintains that for every passionate user out evangelizing {insert preferred methodology name here} to everyone they meet, a koolaid-hunter will do his (or her) best to make sure everyone knows that your passionate users have lost their minds. That they're victim of fads and marketing hype.
If you create passionate users, you have to expect passionate detractors. You should welcome their appearance in blogs, forums, and user groups. It means you've arrived. Forget the tipping point--if you want to measure passion, look for the koolaid point.Sierra noted that the most popular and well-loved companies, products, and causes have the strongest opponents, lauded by cohorts for having the nerve to speak out, even as the thing railed against gains momentum. She included Apple, Extreme Programming and Java in her list of entities with both fan clubs and strong opposition camps.
So, should we ignore detractors? Sierra reminded us that somewhere in their complaints we can likely find hints on places to improve - something that could feed quite naturally into our cycles of do-inspect-adapt. On the other hand, she warned, catering to them leads to the "Zone of Mediocrity", where we try to get everyone to love what we do... at which point, she explained "You're screwed".

The Agile software development approach will never be embraced by everyone - nor should it be. Agile software development simply is not the Silver Bullet that will magically solve everyone's software development woes. But, in the appropriate contexts, it has helped teams achieve some outstanding successes.
Sadly, Sierra has recently experienced the dark side of the Kool-Aid effect herself, with the incidental side-effect of increased readership on her blog, hence the resurrection of this useful and timely old post. Sierra is co-creator of the Head First book series (Head First Java, Head First EJB, Head First Servlets and JSP, and Head First Design Patterns), founded the successful Javaranch.com community, is a master trainer for Sun Microsystems, and a popular blogger on software useability issues.
