(No really, I get the last word on comments because none of you jerks are allowed to comment on this piece)
From my own About Page:
For technical pieces I keep comments open because dissenting views or outright corrections are incredibly valuable if they’re in the same place as the source material. For opinion pieces, which seems to be the bulk these days, I’ll be closing comments.
My position is that if you’re presenting technical or data-driven analysis then commentary on the same page is invaluable. If you’re expressing your opinion with regards to data or current trends then immediate commentary on the same page is far less valuable and, most likely, will simply be argumentative. Take it up on your own forum.
Don’t make me comment all over your site about this.
