> There can be only one /r/science, That's a design choice. Generic broadcast is easier to implement than personalization. It's been known to be a poor design choice for large-scale social media since before USENET's Eternal September. It was especially clear each September before. But broadcast is easy, so here we still are on reddit/HN. Personalization is the design concept that different people see different content in the "same place". Or even the same person, but at different times of day, with their varying preferences. When you want to relax with puns, you can see puns. And when you wish to ask or answer inexpert questions, you can do that. And when you wish to see only high-quality expert discussion, you can see only that. So shifts in demographics needn't destabilize communities. "When calculating my view, severely deemphasize input from people who have joined since September." Bad needn't drive out good. We've known how to do this better for decades. And it's very important for society. But... here we still are. Here we still choose to be. Someone please please disrupt this.
