Come on you know what he means. Blog posts, articles, that sort of thing. AI has definitely made reading things posted to HN a much worse experience (even if they aren't all slop). It doesn't seem to have infected the comments yet, mercifully. I guess for a quick comment it's still easier to write it yourself than get Claude to do it.
It has infected the comments. Our patrons are fighting a good fight, but good slop is mostly indistinguishable from a worthless karma-farming comment. Mods are probably just cheating because there are people with 15-20 year old accounts, many of whom they personally know, and you can assume that the stuff they're interacting with is not slop or is at least worthy slop.
