“I think the existing, altruistic, free version of Reddit will continue to exist and grow and thrive just the way it has,” Huffman said. “But now we will unlock the door for new use cases, new types of subreddits that can be built that may have exclusive content or private areas, things of that nature.”
What would be the point? Reddit doesn’t make any content. They’re just a platform. If they go ahead and paywall subs, those subs are going to have a tiny potential subscriber base. Therefore, they will be less attractive to post to (smaller audience, fewer upvotes etc).
About the only place I can maybe see it working is AskHistorians. And you pay the Historians to answer the questions. Which would of course reduce the amount Reddit takes from the paywall. Doesn’t seem worth it, to me.
Even then, I think the Historians would rather reply in a new free sub with wider readership than take $20 for putting in three hours of work responding to something. They do it because they’re passionate. Not for money.
