Warnock's first case doesn't seem to apply to modern social media? A "perfect" post that doesn't warrant a comment will simply get upvoted / liked / boosted / etc. And in a sufficiently large community, there are plenty of people willing to say "This" or "I agree" even if that doesn't add much to the conversation.
I have a related problem in my personal life: in social situations with my wife, I sometimes make a joke that gets crickets. She will wait a minute, then make the same joke…and get a huge response. One of the drawbacks of being married to someone who is more likeable/has a better comedic timing than you.
What do you think is the intention behind repeating the same joke? Does it to give you gratification knowing the joke is a good idea, even if people don’t like your delivery? Kind of like how many of the #1 hit songs are written by the same Swedish guys you never heard of?
Is there a similar dilemma for comments? If you are in discussion (or argument) with someone online and they stop responding, is it because they have become convinced? Is it because they have come to the conclusion that they are wasting their time trying to convince you that you are wrong? Did they get bored and wander off? Are they busy or go to sleep and might respond later? Did something happen to them?
Ah, this relates to what I call the Helveticomment (see profile).
For general situations, I'd guess there are at least 5-10 more really good types of interpretations to be explored, on top of Warnock's originals. (And on top of the others suggested in the article)
... may have many quite different causes, such as some unusual activity (much more posts nearly simultaneously published, also "for various reasons"), bug, shadow banning...
First time I'm learning about this. Is it possible to take content that falls into this category and then reformulate it so that it produces more responses?
