You probably realise that this website has a voting system (that’s what the small icons next to all comments do; they are not meant to be triangles but arrows). Through this voting system users can show their support or disapproval of any content posted by other users. When a majority of users consistently upvote the same set of opinions positively, you can tell how that majority feels about some matter.

Assuming everyone actually does vote, which seems like a large assumption to make. Maybe what, 10% of people browsing/commentating actually votes? Less? So you have a small intersection much less than "majority of users".

Just read what people read, stop caring about irrelevant numbers, and participate faithfully in the discussions, the points matters nothing, either for if the comment is true or not, or if the rest of the HN community likes the comment or not, it simply doesn't matter.
