I like the video. I do treasure those 2-3 second pauses, before moving forward.
Maybe if he had a small (quiet) sip of coffee before continuing to the next part, that would be enough for some of us to have that little pause to think and then go, "ok, I am following. hmm. yes, I get it".. and then together we move on to the next part.
Also not everyone has english as their first language, eventhough most people can still follow an english video if it is not rushed.
One of my largest pet peeves (lol), since we're on the subject, is those beyondbitcoin talks where the speaker (like in Peerplays) is constantly studdering with lots of "um, um, um, um" this and "and and and and" that...
As key people who are promoting BTS and related things, quite often it is easy to put the material out there. I find very rarely do speakers or videographers re-watch their video, or listen to their archived mumble session 3 or 4 times and realize..
Wow, if I had just paused inbetween my sentences, even for 2 or 3 seconds before moving on, how that might have helped. I know the urge is to unload the information in my mind as quick as possible, and get to the point. The problem is that it comes off as "unloading information", and we don't want to feel like we're delivering an avalanche of information, eventhough that is the end goal.
It can't seem like an avalanche of information. So breathe, take time to pause, the audience will digest better.
