You might think this has nothing to do with online learning, but you'd be wrong. This is online learning. Sure, it's not an online course or program, but regular readers will know I've long advocated for a much wider definition of online learning. This article, and the recent popularity of pandemic sourdough, is a case in point. It's clearly written, even though it throws some heavy scientific terms at the reader, and most people (myself included) will come away knowing more than they did before reading it. A few people will be inspired to investigate further and (like my wife) master the art. And many people will start reading the article, decide they're not interested, and not finish. That's how online learning works. See also: how to make sourdough starter. Next up: Neapolitan pizza dough.
