May I suggest you use the open threads

That's a good point; thank you for reminding me of that option.

FWIW, by way of codified guidelines, we have this on the About page:

Off-topic top-level posts may be removed.

and this in the FAQ, under "When should I make a top-level post":

if ... you have an important point to make about rationality

Combining those, I see how I got the idea that I shouldn't bother making a top-level post unless I had something particularly new and clever to say about rationality itself.
