I have started reading/using HN from the last 2 months. Here are my takeaways from it.

1.I get to pick and read the highly approved news in the areas of my interest. It cuts down the time I need to spend on other sites. 2. I get curated news from other subjects which I can choose to ignore or sometimes get high level insight into it if it interested me. 3. Because of the quality of readers in HN, it kind of points what is important and what is not. 4. Last and the most important aspect is the comments section which adds more value than the topic.

To capture the gist, the signal to noise ration is high in HN which helps my time.
