And I feel that it's just as dangerous to do that as it is to not repeat yourself enough. After all, in saying something too many times, you're diluting your message. Plus, posting these things on Hacker News is preaching to the choir. The companies that use NDAs probably aren't going to read hacker news. Neither are the "waterfall" developers.
