There are supposedly many introverts frequenting HN and longing for any help they could get in building their network. Some of them probably reflexively upvoted the article without looking at it first. Since it's impossible to un-vote a story, those upvotes remained even as they came back here to complain about lack of meaningful content in the article.

> Since it's impossible to un-vote a story

When I vote a story, an "unvote" button appears to the left of the "parent | context | flag" buttons. Are you saying that it doesn't work?

No... I just honestly didn't notice it's there! Will need to check if it works next time, thanks for the tip :)

The article is shit; I just wanted to encourage more discussion on the topic in the comments.

Many of us upvote seemingly useful titles before reading the article. This one turned out to be clickbait.

Honestly I read this website for the comments 70% of the time.

72 now..

lesson learnt.. clickbait titles is a real thing
