Welcome to the forum! Unfortunately, post deletion is currently disabled due to the original decision made in the Deletion policy thread, though some have since voiced their objections to it. If you want to provide your input on the subject and explain why the ability to delete your post is important to you, you are free to do so on that thread. Sorry about that; I am not happy about the decision, either.
Since I’m here, I might as well comment on your video. I have been busy, so apologies for not doing so earlier.
I found the video to be immediately accessible. I don’t know why you consider the “audio quality” to be “low”; it sounds clear and easily intelligible to me. If you had not mentioned that you filtered out the background noise, I would have assumed that you simply recorded in a quiet room. Your voice is also confident and fitting for an instruction video, something that greatly improves the presentation, especially when the video consists of nothing but image stills and your voice.
It was easy to follow what you were saying and you made sure to not introduce anything technical that is not necessary to accomplish the task the video is about. Naturally, anyone watching it will have to come with some basic knowledge of the relevant concepts to really understand why this is important, but unless you intended to also introduce viewers to the very concept of PGP signatures and verification, this is a reasonable assumption. Even for those who are totally unfamiliar however, blindly following your instructions is sufficient for them to verify the signatures with good confidence, even if they do not fully appreciate what they are doing.
I actually had a paragraph here about omissions that probably do not need inclusion because they are more about high-assurance authentication rather than mere authentication, such as by checking the key’s authenticity with multiple independent sources (as recommended by the Qubes documentation), but you actually covered that in the video! Great job! And even better is that you did not belabor the point or present it confusingly, which is important to get through to those for whom such advice may seem strange if not paranoid.
One addition that might be worth considering is actually not in the video, but in its description, where you include a text tutorial as well, or at least the relevant commands and key IDs, so that viewers can copy and paste the commands rather than type them in by hand. I understand that this is available on the documentation page, but replicating it below your video (with the non-generic commands) may be more convenient to viewers. This too is not necessary, and your video would not be less without it, but it may add to the video without having to edit it.
But really, I have no complaints. I was just surprised that with this level of quality, your channel is not more popular. It seems that you have just started going beyond gaming videos and this video is unlisted though, so I suppose I shouldn’t be.
Thanks for your contribution to the Qubes community. I think it is a great video to share for anyone using Windows and hesitant to read the documentation.
