> this sort of response is baffling to me

I'm struggling to understand the negative tone in your reply to the parent comment. They simply offered an additional resource on the topic. Rather than welcoming it, you seem to have taken issue with it. One of the strengths of HN threads is that people often contribute further material that others may find helpful.

The video is useful but so is the Wiki article. Some readers will prefer the video, some the article, and some both. Why object to someone sharing another link?

In fairness to the GP, the OP has now admitted that they made the post without having watched the video and that they did so out of prejudice against YouTube videos. GP wasn’t objecting to the additional resource but the implication via “Without video:” that the video itself is less valuable.

		As the OP, I agree with everything you said, but I suggest an alternate characterization: Some subset of people, including me, prefer written communication to video (regardless of whether the video is on YouTube or elsewhere). Since my favorite HN threads delve into a topic, rather than into the details of a particular presentation of a topic, and since on seeing this topic raised I hopped over to Wikipedia to refresh my memory on this topic, I thought I would provide a breadcrumb for others of similar mindset to help jumpstart the topical discussion. Which, clearly, I was not quite successful in doing -- so, lesson learned.
