I posed the issue about Agile saying "don't do requirements up front, because they will change" in a forum at http://www.requirementsnetwork.com/ and Scott Ambler himself weighed with the best answer yet on this, so go on over there and check it out. An email conversation with Peter Coffee has also helped me a great deal.
My conclusion is that originators of Agile did not see it as Extreme, but rather as Flexible; that I can understand. So, no more rants from me on Agile... but now I want to what in our profession is still bugging everyone out there. Please leave a comment, and if i get enough stuff, I will publish a "top ten' list.
