Phil amusingly introduces the basketball term “garbage time” to refer to the point where a discussion thread reduces to back-and-forth arguments without much hope of further progress.
That got me thinking how garbage time starts at different points on different blogs. Here at Statistical Modeling, it doesn’t happen much at all. The Freakonomics blog often has high-quality comments (as I discussed here), but there are so many of them that there’s not really a chance for progress to be made in the comment threads. The posts at 538 get lots of comments, but garbage time there usually starts around comment #2 or so.
