I mostly like the reports by people reporting on their field of expertise. The occasional but extremely valuable input from a core developer, an AMA by the CEO from a certain company, boots-in-the-field reports by people benefiting from freedom tech such as Bitcoin or NOSTR, a personal but insightful comment based on your own experience raising a kid, a detailed guide on how you've set up you are managing Lightning liquidity, etc...

Overall, I prefer positive stackers too. A little bit of doomsday reporting is healthy and interesting, but I prefer to believe our future is bright.

My advice would always be to favor quality over quantity. Report on what you know a lot about. If you don't have such knowledge (yet), report on interesting external content, but provide context whenever possible. Links without any quoted text rarely grasp my attention when no context is provided. That's why when I visit Hackernews (less and less, thanks to SN), I often read the first few comments first to know if the article is worth my read. SN provides the additional advantage that you can provide context directly under your linked article as OP.
