If what people here say is right, and AI usage online is growing and accelerating, then by the end of the year, the vast, vast majority articles posted to the internet (and linked by HN readers) are going to be AI slop, at which point it is not going to matter. "This article is AI" is going to add about as much insight to the conversation as "The author used a spell checker."
A good link aggregator should strive to select the <1% of articles that are actually high quality. Who cares what “everyone” is doing?
