I love HN but Blind is more entertaining for sure.
If you don't take it too seriously, it is a fun and entertaining place, also people keep it more real as people don't hold the punches. (due to anonymity).
Also it is a good place to know about tech interviewing in general, what to do, leveling, negotiation. It servers as a mini forum/guild for tech folks. It can be very helpful on that aspect.
On Blind, you can go ahead and claim you make $600k salary working 4 days/week after 18 months of grueling interviews. Write up whatever fan fiction as long as it makes sense.
