Interesting, I was always thinking that audio/visual information is naturally much easier to consume. For instance: I can watch a video and count to 10 in my head at the same time – I will still get everything what was in that video – but with text it's a much harder task since the head is fully occupied with "narrating" the text what I'm reading, so reading in the end turns into podcast inside the head before actually get consumed.
I find it much easier to skim texts to find the information I'm looking for. I can't do that with videos unless they have clearly marked chapters.
When I read about a new technology and they have a video instead of a blog post, I just close the browser. If it is useful, someone will probably post a blog on HN at some point in time
