Because I can't read all content to judge its value.

I used to use other signals to help judge: literacy, reputation of the writer or publisher, the media they used to communicate. Now even governments are distributing notice of official policy through poorly written tweets, yet the Internet is flooded with whole websites of AI slop that looks on the surface to be professionally made. We lost the signals that used to help us filter out the signal from the noise.

The alternative is not to read all content carefully because we don't have anywhere near the bandwidth to do so. This article is about other ways we can provide those signals. Even if the content is crap, the fact that someone has to sacrifice to produce it limits the amount they can produce, requiring them to prioritize what they produce, and signaling that this was important enough to them that it was worth the sacrifice.
