1. Would you watch this to the end, if the whole thing were twice as long as this excerpt? (The remainder would be a walkthrough of what the print statements show, plus a diagram - similar to the one at 2:32 to 5:56 - that explains a gotcha with containers like NSArray.)
2. Would it be interesting enough to watch if it used a program contrived to show just the bug and nothing else? (This would contain the two diagrams of how RubyCocoa works, plus a shorter description of the code. Perhaps 8 minutes total.)
3. Should I just give up?
4. Should I not only give up on this, but also on ever considering doing a screencast ever again?
