It’s always good to keep one’s shill detector up on Ars vis-a-vis Reddit given the ownership situation. I’ve so far not seen anything that rises to that level, including here, because of the audience. If you’re on Ars and don’t know what Reddit is, this story isn’t going to be of interest and thus is not going to push you to try using Reddit.
That said, this story only seems relevant to the minuscule-if-at-all-extant sliver of Ars readers who know what Reddit is and haven’t been using it only because they’ve been waiting to hear what paid apps look like eight months after the whole fiasco started. That’s not a demographic I’ve ever seen represented in the comments.
