It's not a true knowledge sharing platform, it's just a popularity platform where being the first to write about the new ANGULAR version 9999 is seen as a sign of great wisdom and being "on top of your game as a dev".
I wrote there a lot and stopped exactly due to the misalignment between what I wanted to consume and write about.
More generally, I find that ad-hoc aggregator websites like HN have a much higher hit ratio with my own interests. Also, if you're a professional developer actively involved in open-source and working within the JS/TS ecosystem you'll likely get a bit more value out of dev.to than I did, I guess it's just not my style...
