Thank you everyone. The final version should be a lot better.
Yes, aarti, there are over a minute of credits. We'll probably make them go by faster in the long version to make room for some of the extra scenes -- so it may, in fact, not be much longer over all.
The only way to target people on YouTube is in the tags you type in, to attract people's attention when they do searches. We used fantasy, magic, wizards, etc.
There have been over 500 views already, but I think the vast majority have come through personal contacts -- mine, John's, and our cast of actors. Now that everyone's family, friends, and coworkers have seen the thing, I expect the number of views to drop to only a handful a day.
