The hivemind doesn't agree with itself on anything, so that can't be it.

A comment is unsubstantive if it doesn't include any more information than 'boo' or 'yay'. (Although polite empty comments like congratulating someone are just fine.) On HN we want discussions where readers can learn a bit more than that someone likes mining.

Edit: another unsubstantive comment you posted was https://news.ycombinator.com/item?id=17672125, which was worse because it invokes the uncivil why-dont-you-move-to-another-country-then internet trope. Can you please review https://news.ycombinator.com/newsguidelines.html and follow the rules more carefully here?
