You are correct. I was a bit too general. I said “most signaling”, not all, but that probably goes too far. I clarified in another comment that I specifically dislike disingenuous signaling, as well as excessive effort spent on signaling alone rather than whatever substantive thing it is you’re trying to advertise.

I regret my original wording. I think I should have jumped directly to my main question about whether or not people are as unaware of signaling as the article suggests.
