Re: the glorification of reading.

I've thought about this. I agree with you not all reading is equal, and reading social posts (including HN) is the equivalent of junk food, but there's something about reading that sets it apart. I think it's like exercising. Reading engages parts of the mind not exercised otherwise, it requires a more active imagination, it often involves "adult" mechanisms like delayed gratification that are less present in other forms of communication. It's more active and less frictionless than many internet activities, watching TV, etc. That's why it's sometimes a struggle to find a moment to read, and why young people often don't do it: it requires more effort than competing activities (this struggle also applies to physical activity, of course!). And this effort does something positive to your brain, I think. I'd say given two forms of trash entertainment, one trashy literature, and the other a trashy TV show, the former is better for you than the latter.

Just in case anyone wants to debate this, I am NOT saying watching TV is completely frictionless or requires no imagination at all, and of course there's a lot of variance in which specific show or movie. I'm only arguing in relative terms.
