I understand your point of view about polishing, and from the other comments too it is a common theme.
I believe polishing will be needed, but that doesn't exclude the creation of also unpolished worked.
From all the feedback gathered I will:
1. Live stream the unpolished work, this will help creating a sense of community and people would be able to be part of the short feedback loop
2. Collect the most interesting parts from point 1 and create polished videos
3. Write articles for whom prefers this media
Regarding the audience I'm not thinking of mid-senior developers that like to watch something on the second screen while working
