Yeah these things are all pretty relative of the reader's perspective. FWIW I mean this specifically for the less technical threads. Technical threads still seem to rank contributions appropriately. But the moment you touch on something more cultural, like the long term computer thread, or the Mr Beast thread from the other day, you get a lot of pretty low signal comments that get a lot of karma. I do find that the very top of the comments page stays okay but the moment you get past the very top you get lots of low effort comments.
