I usually don't care for screencasts about technology because they often treat the viewer like a dumbass. For example, they'll spend 30 seconds introducing themselves or explaining what they're going to do even if it's super trivial. I would suggest trying to be as concise, but still be as digestible as possible. If your screencast is actually useful and 5 minutes long, I might watch it again. If it's 10 minutes and just okay, no way am I going back to it. Hope this helps. I'm also interested. I am learning ruby now and soon I want to start learning rails.
