When I was first introduced to timing diagrams, I thought of them as like scope traces and understood them right away. I was in 3rd grade at the time, regularly reading electronics books to learn.
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

1/10th the number of views after the same time period as my previous video  :-+

What conclusion can you draw from that observation? Does it dissuade you from making more like it? The thumbs up suggests not but I suspect it has an element of sarcasm attached.

Sarcasm detected correctly.
I'm not the least bit surprised, seen it happen countless times over the years, just another example of niche educational material getting very few views. I didn't expect this low though in this case, probably the worst performing video I can recall.
It's a topic few understand that they really should need to know this stuff, so they are like "oh, timing diagrams, what do I need to know that for?, I'll skip that one", compared to say a mainstream topic like opamps or zener diodes.
Maybe a better title could have doubled the views, hard to know. Well, actually, I do know, a title like "The one design thing you really need to know!" or something similar would have at least gotten normal views. But of course you can't do that for every such otherwise boring topic video.
The 100+ times it's happened before hasn't stopped me from making more, I just continue to do what I always do, make whatever I want. Just pointing out that's what happens.

Niche != bad. If only the "right" people watch them, then niche == good.

Maybe most people already know them and so skip the video, but those that don't really appreciate that video? The older I get the more I appreciate knowing I would get no benefit from readign/watching something!
There are lies, damned lies, statistics - and ADC/DAC specs.

 I seldom fail to find some value. I haven't watched this yet, but it's a time thing, not because I don't plan on watching this. I learned timing diagrams eons ago, but just like some of Dave's other fundamentals videos, a fresh take on it will likely result in one or more eureka moments.
 My other hobby is model trains. I was recently at a show that had various presentations, one of the first ones was on how to model a locomotive that our shared interest railroad acquired in 1974. I model the 19050's. Still I sat through this presentation because, as I remarked to the presenter and the show organizer afterwards, even though I will never build this exact locomotive, there is always something to learn that you can apply to ANY model. I happen to be in HO, the most popular scale, but I see it in model magazines all the time, people who model in one scale complaining that there is never enough material in their scale. Short-sighted, I say. Just because the example was built to one size does NOT mean you can't use the same methods to make it in any size you want.
 Too many people with tunnel vision. Think outside the box, and also don't assume you know everything about a subject. I may be on the older side, but I am always learning. Yes, you have to draw the line somewhere, I am unlikely to watch a video telling me how to calculate series and parallel resistors, or how to read the color code on resistors (although if someone has a way to actually see the muted colors where so many look alike on many modern resistors, I'm all ears - any more I just measure them because it seems brown, black, red, and sometimes orange all look the same these days - and I am NOT colorblind).

Dave, as I do not have a You Tube account have a virtual thumbs up

With my very limited experience with electronics I think I saw most of what Dave described, confirming that timing diagrams are all over digital chip datasheets.

The thing that often rubs me the wrong way is not the (lack of) number of views, it's when people say "do another fundamentals" video so I do one and half the feedback isn't about that video, it's just "can you do one on xxxxx topic". They won't thank you for that one, it's just "give me what I want".
For those who don't know, being a Youtube creator is all about the feedback you get, that's why we enable comments and thumbs.
I can't imagine the world of not having comments enabled, like it's been forced for all the kids content channels now, that must be depressing. But I guess the big cheque must make up for it.
So, pro tip, next time you see your favorite content creator you like make the style of content you like, but you didn't get anything out of that particular video, drop an encouraging comment anyway, even if it's the truth like "Hey, I didn't personally learn anything from this video, but I really appreciate this type of content, so please keep it up."

Wow, I just searched Youtube for "timing diagram" and there is a large number of videos about the 8085 for some reason  :o

I have always watched the 'educational' videos. Sometimes several times, I am a bit slow!
At my amateur radio club educational meetings - I am one of the guys trying to find new content to present. Your educational videos along with those from W2AEW etc, have always been well received.
I appreciate the effort.

Whoah! Watch where that landed we might need it later.

I haven't watched the video yet. It is a timely video on timing diagrams (not as good a pun as I'd hoped). I could benefit from some education on them so I'm saving it for when I have time to digest it properly.

Dave dances around what he is talking about its hard to define what he is on about.  Big thumbs down.  Dave need to get a real job.

I don't have an easy solution to this dilemma. Perhaps a clue is in your OP amp video which gets good viewership. If you pick basic fundamental friday topics with keywords that will trigger search hits for those million(s) of students in ee and etech courses that are struggling. These type of videos may not appeal to you and if your heart is not in it, it will show. In some of your videos you are in an ebullient and irreverent happy mood, I am thinking in particular of a mailbag monday a few months back and these are fun to watch even if I am not interested in the items you are reviewing.

Agreed. It is also worth doing that in real life, e.g. when you have a particularly good cup of coffee, or find a

I rarely have enough time/patience to watch videos, since almost all aren't sufficiently information dense, and it is difficult to skip past the uninteresting waffle to find useful nuggets (if they even exist).

And you need to piss right off.
Let's see your video on timing diagrams.
But let me guess, you've never produced content in your entire life, right?

You're always going to get people that don't like your style or content; I imagine you reconciled to that!.

But there's neither reason nor benefit from their being rude, and they should be called out for that.
