The articles linked to in HN aren't always the most fruitful, whereas the comments are a universe of wonderful discussion. I've learned dozens of things from browsing the comments here, which makes sense as we have world experts in dozens of fields who are regular commenters.

I usually get my HackerNews updated through the feed in Telegram, which means I usually go straight to the comments before even reading the article. Reading them is really nice, as it lets me gauge if I think the article is worth a read, then engage in some great conversations about it.

This is why I keep coming back. It is not unusual to see world leading scientists, book authors, and startup CEOs in a quick browse of the comments. The kind of people you want to be at dinner party conversation with, if your goal is intense technical discussion.
