Yes, I do.  I consider comment length and unique comments.  There are
certainly better ways to measure comment quality.  How would you do
it?

My formula strips the digits from all comments.  That penalizes the
editor that uses a bounding box as a comment, but I'm fine with that.
A bounding box is a terrible comment. :-)  Then I count comment
characters, unique comments and comments only since API 0.6 was
deployed. There were no changeset comments before that.  My formula
considers comment length and uniqueness.  There is probably room to
consider comment rate as well.

Yes.  What is unclear to me is where the floor should be for good
comments? 5? 10?  20?  It will vary by situation, obviously.  One bad
comment doesn't make a bad mapper.  Don't take this too seriously.
