I don't think so. I did not break it, so it is not my responsibility to fix it. And I am not a supporter of the concept of collective writing with everyone empowered to amend, add, delete without geting the approval of the original authors. I assume total responsibility for what I write, and I don't allow anyone to tamper with my text. I will consider suggestions, criticisms, etc. but I am the ultimate judge of what, if anything, needs to be changed.
