maybe it would be interesting to include an addendum

What I'm actually intending to do, once it seems like we have all the major criticisms we're going to get, is to add comments inline after the summary of what DGW say about each principle. I think that's a little better than an addendum at the end.

I imagine you meant to write 'when'.

I did. I'll fix it. [EDITED to add: Now fixed. Thanks.]
