Well for starters this is hardly a motion control system, it's a glorified remote control car with a lift on it. Secondly I was making a general statement about the use of the word affordable on the site, not about this article.
My favourite part of this site is seeing the word "affordable" in article titles and playing the fun game of guessing how many kidneys that means you need to sell
I did a painting once where i just sprayed the paint into people's faces and then hit them over the head with the canvas. Everyone said they found the experience "jarring" and "hyperreal". I just told them that they weren't good enough for the medium.
$270 for a 13" slider, jeez people will buy anything these days.
Panasonic 12-35mm all day long, its an amazing lens
An interesting angle. I'm sure that their are multiple "tiers" of people who watch YouTube videos though. As stated above, some people like the personality aspect and some people (who may be starting out or are just interested in the information) will find the lighter style of the people you mention useful. I think we have to remember that it is their jobs to be content creators as well, you wouldn't see Roger Deakins setting up a YouTube channel and Vlogging his methods for instance as obviously he's a working professional.
I guess in summary, I take your point that its often more show than content but i guess that's the nature of their jobs and it's useful to some people. I'd guess if it's not useful to you then you've moved past the level that they're aiming at.
