This question was asked and closed today as off-topic due to being a "lists of works or recommendations" question. In the comments, the author asks why his question was labeled off-topic while this very similar question was on-topic. I'll go further and ask why today's question was mostly down-voted while the older question was pretty well-received vote-wise.
I can't really tell a difference between the spirit of the two questions. So did the standard for what constitutes a "lists of works or recommendations" question change? Or is it a case of "people were feeling more forgiving that day"?
