So why is this surfacing again now and why not a up to date article on Oxy? Which sounds very useful btw.
But I might have encountered this problem or am about to, and such a post might resonate more.
It is like advertising in a way. But for knowledge. As long as people upvote it, it's resonating.
So, what's the threshold for what should be shared, given that most people don't know most thing things...?
I also think HN does some sort of deduplication if something has been posted recently (to count as upvote instead of new submission), but not sure of the details.
Isn’t that the whole benefit of sites like HN and Reddit?
