this guy makes some great content

I'm newish to youtube.

I'm fairly newish as well (don't use or really understand facebook and twitter but OK with forums and newsgroups) but find videos on technical matters to be such an inappropriate medium that I will only look at one when I have no option. I spent perhaps 30 seconds skimming the posted video which is typical for one that I find interesting! What brings someone to view all of a technical video from beginning to end?

The first time I came across the phenomenon was 10 or 20 years ago when I needed some detailed technical information about a computer board but could only find a video on the manufacturer's site and not a technical document. After wasting time jumping about the video to find what I needed I was sufficiently motivated to enquire about why there was no technical document. The reason seemed to be that they had to make a video because a proportion of the audience they wanted to reach could not read. Given the existence of the video the additional cost for a technical document covering the same information was not considered worthwhile.

This makes me rather curious about the audience that those that make technical videos are trying to reach. A modest quality video is obviously going to be cheaper and easier to make than an equivalent technical document. Can youngsters get along with technical information in videos significantly better than us oldsters?

(If you haven't guessed I am thinking about making some technical information for the web.)
 
We benefit as much from seeing the practical implementation of something, as we do from reading about it's theory.

Yes for practical information like how to lay paving slabs but even for this an indexed set of clips would be more useful for readers. The above video however is (I think having only briefly skimmed it) trying to get across a range of technical topics that would be significantly better presented with the written word and a few pictures and/or clips. i am not querying the content just the reasons behind choice of format.
 
What's a youngster these days?

Someone that would watch a flim on a mobile phone? Or as a group would watch a film on a 15" laptop (current advert)?

The popularity of the DIY speaker group on facebook baffles me as well (I have tried to use facebook!). It is very difficult to follow the evolution of threads compared to a web forum and yet this type of format is popular. Why?

There appears to be something that I just don't get or can't see concerning why formats that are clearly poor at efficiently getting across some relevant information compared to their "predecessors" seems to be successfully displacing them. I believe I can work out why I don't like youngster's music but this baffles me.
 
I find this discussion quite funny.

If "youngsters" like myself prefer to study for our university exams by literature only and don't show up to lectures at all, especially the older Professors feel underappreciated and often blame it on our generation and our preferences.

And here some propose it's the other way round. The youngsters can't read and watching is preferred.

And what do we learn from that? Overgeneralization bad.

Because it's a total free-for-all? I'm also answering questions with questions, this is easy........
