HN audience prefers text to video; videos rarely do well here compared to other sites.

Video content, particularly on youtube, gets very little traction here generally.

I watch his videos, but not from links here and that is probably what you are seeing: those of us who might follow your link have already seen the video (likely via grayjay rather than youtube) and will skip over it to the next interesting new thing. People who don't already watch him will see “[video] (youtube.com), 1 point, discuss” and think “oh, another video that could be a few paragraphs of text which would be much faster to read than watch, that so far no one else has seen as worth interacting with, preceded by two unskippable adverts”.

A link to youtube is only going to get much attention if it is lucky to have a title that jumps out to a few people so it gains the first few votes and/or comments that get the ball rolling. Even then Louis' videos aren't going to get a hot debate going: most people either entirely agree so don't see the point commenting further, or they aren't the sort of people who are reading HN at all or are but don't follow video links.

Oh that guy, I like him.

He puts his money where his mouth is too. Weighing in and challenging people to sue. Good guy, intense but good.

I think it is a shame youtube is forcing creators into longer videos

I watch long form videos on topics I care about. If I care about the topic, I likely have already seen the videos. But I'm not going to watch a 20 minute video posted to HN to discuss it. If it's not something I can skim over in 3 minutes, it's too long. Take the post we're on right now. You can read through the entire contents of the article in 1 minute.

Unless the video is about an extraordinary natural phenomenon that can be seen, video (and audio) is strictly inferior to text for communicating information.

I clicked on one, he was rambling about wearing sunglasses because of studio lights, seems like pointless drivel, so I stopped watching.

Voting on hackernews is a bit weird compared to reddit. The whole UI is strange to me.

Having said that, I noticed that there is in general too much content to consistently e. g. vote or do similar actions. I was watching Rossman's video almost daily in the past; stopped doing so a while ago simply because of lack of time on my part. I need to choose more carefully where I invest my time. (Also, for some reason, when Rossman was in New York, his videos had a better punch; not sure if I am the only one noticing this but he seemed to have a better focus when he was still in New York, even though I understand he relocated, to stop getting milked by politicians in New York.)
