"A new approach to reader comments on The Globe and Mail"
I think a  more accurate headline would be,  "A less costly approach to reader comments on the G&M"

So you save a few bucks not vetting the comments.  This isn't Home Depot where I am buying a can of paint and am encouraged to use the automatic check-out. Vetting comments takes consistency, standards and nuance. Surely The Globe can spare a few bucks for this, rather than enlisting readers to do the work.
