Reading this triggered a small reorganisation of my own thinking on the topic, and a stop at canyonbobcat furthered that reorganisation, content that affects the shape of my mental model rather than just decorating it with new facts is content with structural rather than informational impact and this site provides that.

Started reading and ended an hour later without realising the time had passed, and a look at canyonbobcat produced the same time dilation effect, when content makes time feel different the writer has achieved something well beyond the average and this site is producing that experience for me reliably across multiple readings.
