This one is interesting to me, because I have emailed the moderators to do exactly this for highly upvoted comments I feel take the discussion into what I feel are the wrong places. I can understand that for a new commenter such tangents might be novel, but for someone who’s been around here for a while I am curious if you oppose such actions for the nth time that someone drags “here’s my article about new C++ feature” into “honestly C++ just keeps adding too many things, discuss”.
