Link to medium about the Big Belly's that got installed and how we maintain them.
That's rather presumptuous, it is of interest to me.
And considering the previous post from last year received 100+ upvotes and 100+ comments, I think it's safe to say that it's of interest to others as well.
I don't know about that. Last year the OP and friends worked to pick up and document trash and now, a year later, that information has been used to make informed decisions about how to keep our streets - and society - cleaner.
I'd argue that OP has quite definitively _contributed to society_.
If he'd just posted "I picked up some trash" - I could understand your comments, but he's done the work, gathered data, written about it, etc. So w/r/t to _teaching something_, I know more now than I did before reading his post.
Quite frankly, I could attempt to compare your contributions to society (aside from the snarky, dismissive comments on HN) but you've opted to hide behind a new, anonymous account. If you believe a submission is off-topic, just flag it, creating a new throwaway account just to disparage it seems a bit extreme.
And please understand, I don't say this to disparage you or insult your incredible intellect - just in the hope that perhaps I can _expand your views_ on how OP's submission is of interest to members of this community.
