Disagree with that change, also the change from "world's largest dialogue" to "a dialogue" (though it looks like that bit of editorialization came from the original submitter). IMO the original title of the article is the most accurate and is not linkbait. There absolutely is something about Reddit that has sparked an unprecedented direct line between "notable people" (for lack of a better term, but it applies to more than scientists) and the wider audience of their work, and that's what the article is about. The current title is neutered to uselessness - how did Reddit "host a dialogue?" Well, simply by existing as a public web forum. And apparently to some that's all it is, no different from any other, but that pretty obtusely misses the cultural phenomenon that is undoubtedly happening there. It's been a few years since I visited Reddit regularly, so I'm not a fanboy, but I can still recognize that, whether intentionally or inadvertently, their platform has enabled something that didn't quite exist before (in a sociological sense, if not a technical one).
