I agree exactly. A concept like "agile" is a great way of organising your own thoughts. Inventing words and concepts is a powerful tool. But... we have to remember that we invented them. They aren't real. That's easier when you invented them yourself.

After a while... it's like the cliché about taxi drivers investing in startups... Sign it's time to get out. When people I know have no idea start talking about the awesomeness of some abstract methodology... I'm out.
