First, a little background: Windows 3 Animated Background/Desktop/Wallpaper was a question I had myself tried hard to answer, back when it was posted. Recently however I came across Jeff Atwood's Let’s Play The Guessing Game SE blog post. Considering that (to me) the question above (although it has a single, definitive answer) looked to be a perfect example of what Jeff was talking about, I first flagged it so a mod would decide, and when that was declined voted to close as per the mod's own suggestion. I also suggested that other questions tagged software-identification ought to be closely looked at and closed if required, and What software did distributed, encrypted and shared storage? actually was.
In an extended discussion with Synetech (due apologies to him for dragging him into this), I was informed that my assumption - that Jeff's views implied an SE-wide policy to disallow "Guessing Game" type questions - was incorrect: "Identification questions are not universally shunned. For example, Arqade eventually voted to block them, but Movies/TV embraces them. SU doesn’t have a specific policy..."
So what I want to know is - how should we treat such questions here on SU?
