Effectively, an edited collection of the news over the course of a year has a low SNR compared to that of following the constant stream of instant-news. The point was expressed badly, but it's about the way that the average quality of new-stuff is a lot lower than the average quality of a curated set of high-quality stuff from a time pe…
