I thought it served as a useful placeholder, for a given point of view and our response to that.
Of course, it really belonged on this site (meta).
I'm not requesting undeletion. I'm hoping to hear views. Part of my interest here is that I feel that our current definitions of what's on or off topic are under strain at the moment, so the more discussion the better.
Now that Gary has undeleted it, all users can see it for themselves. Also we can see that it's had (at time of writing) 143 views. Not a lot, but more than many legitimate questions.
It's clearly off topic, but the (implicit) real question I'm asking is Should we delete such off topic posts? Do they serve any purpose?
I think that off topic posts add value to our site by showing examples of what is off topic, of poor quality questions. They could even be used as duplicates when closing related questions.
At the time of writing, the debate is on the side of Gary's initial judgment and the view expressed by Móż.
