One problem is licensing.
I like to post links to music videos in comments and even got some upvotes for
https://www.youtube.com/watch?v=VDFx8hJY5x8
But I hear from many people outside the U.S. that that video does not play for them (tell us if you can play it here!)
Also I think I can size up a text article to know if I want to read it in just a few seconds compared to a video that I may have to watch a few minutes of. Also I can read text articles in more situations (do what you want but I do not wear headphones for safety’s sake when I am out in the city or on the trail) but I can browse HN and most web sites rapid-fire on my tablet on the bus.
