I only read fiction or low-density non-fiction books now, any of the denser non-fiction books that aren't considered classics usually are full of fluff. For that, I heavily rely on Blinkist, which is basically like Cliff Notes as an audiobook.

There's just way too much fluff stuffed into a lot of the books you see marketed for professionals to read, in particular. I definitely enjoy the quality of prose in classic works of non-fiction, especially histories, but most of the new stuff I'd never make it through without a summarization app.

I guess I'm almost the opposite, I read HN every day, and I usually read the articles, and then that's about it. I might check article of the day on Wikipedia. I just don't read as much anymore unless it's for enjoyment, which is usually fiction.
