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.
