You may well be right, it's hard to tell. I don't see an easy way of finding out short of people replying like you have. I assumed that there enough of those who would react to make the effect visible, and I don't see how someone agreeing with wedrifid's assessment would go back and upvote my original comment, so even a partial effect could be visible. But anyway, this is not important enough to continue discussing, I think. Tapping out.
