Too slow, very seldom well done, too slow, can't link through to other things and come back, too slow, usually don't have want I actually want, too slow, can't skim, too slow, purely linear, and too slow.

And they're too slow.

I read really, really fast, and the ability to skim, pick what I want, follow a link, and get to the real question is totally blocked and prevented by video.

Additionally, they don't engage me. They are intended for a passive audience. People think they remember lots from videos, but I seem to remember some research that suggests that they don't. You might Google for terms such as video, engagement, learning, retention rates, etc.

I've got to go, but here's an offer. If you trust me, email me what you're trying to explain, and I'll tell you what I think is unclear, and get my wife (who is capable but not technical) to do the same. We'll tell no one about it, and you'll get an alternative point of view.

I'm really busy and have very little time, but I don't like being purely negative, hence the offer.
