It depends on your medium, many platforms require a lot of throughput in order to rank highly in their algorithms and reach people.

If your business requires volume not high value customers then you need to play the volume game. But if you have high lifetime value customers, you could get away with fewer articles of higher value, authoritive, trust and reputation building content.

Eventually, under the barrage of AI spam, the sites which "uprank" using "posting volume" metrics will lose users who will see the quality of the content drop like a rock. Other sites, which have better algorithms which are tuned for quality not quantity, will take over and you will be able to post quality content there instead. I think HN is one such place, I often see companies post high-quality content just once or twice a year and it reaches here pretty well.
