◇In your "History of Japan" video, there were a variety of "corrections" that you made (through "annotations") after you put the video on youtube. Unfortunately, these annotations are Only available on youtube, meaning the downloadable version on your website is "More False," and therefore to some, "Not As Good." But, I enjoy having a version on my computer! You may have considered some options to prevent a situation where you have to add annotations, but have you considered-
Releasing a version that you're satisfied with to the people who read this "estqunois" page, so that they can catch the things you might not have, and then incorporating those edits into a "Final Version" that you upload to youtube? I know you're not sure about collaborations, but but adding the annotations was a "Collaboration" of sorts; And, you seem to be accustomed to the input of the "people" on this page already. There are a bunch of problems with this, but it would be an interesting experiment- maybe a shorter Longvideo would work better...? Good luck with the rest of the video.
in order to get any sufficient results from 'beta viewers,' i would have to release it to so many beta viewers that it would constitute a full blown leak. many of the complaints that people have are things that might only come from 1 in 10,000 people. no matter how many beta viewers view it, there will always be more things for people to notice later
