In reply to UKC Articles:
I think that those criticising are being a little short-sighted. Yes, perhaps it isn't quite right for you. And yes, there do seem to be a large number of sponsored instructional videos. But, just because you're 'better than it' doesn't mean it isn't useful for others.
I quote the description of the video verbatim: "We hope you find this series useful for learning basics...". Add to that the fact that the first words of the video are "Beginner's trad tips".
With those opening gambits I don't think there was ever a case for thinking it was going to be particularly high level. As such, why complain about it - it's only doing what it says on the tin, after all.
