 Misdirected Debate 

The threads on this entry have gotten misdirected in a zealous comparison with MPT, which is interesting but not especially relevant.  Perhaps the word ""Portfolio"" has become a flash point, but I see only limited value in that line of discussion.  It's a footnote and only loosely related to the issues addressed by PPM.  I agree with Nickmalik that a more practical definition would be useful.
