PSA: If you want there to be a new Stupid Questions Open Thread, make it yourself! There is not and never has been a rule against this. I consider the "how often to make them" question unanswered, but a good interim answer is, "whenever someone feels like making one".

(Also, my computer broke, and so I posted this from a Wii, which is incapable of using the article editor. If someone could kindly edit "the sentence" into the post.)
