“Others’ comments” 

I didn't edit your comments.  But if citing the guideline floats your boat, here are some helpful tit-bits from the same page you linked:

 “The purpose of a Wikipedia talk page is to provide space for editors to discuss changes to its associated article or project page”
 “Keep on topic”
 “Start new topics at the bottom of the page”
 “Make a new heading for a new topic”
 “Create subsections if helpful”

And the guideline explicitly permits “deleting material not relevant to improving the article,” so perhaps I should just have zapped your comment. — Z. 2009-02-02 20:34 z
