It's much easier to remove text and is something that an editor would probably suggest. I really like the idea you have ... demonstration through video - very effective. Reminds me a lot of say Google ( http://video.google.com/videosearch?q=genre%3Aeducational+so... ) or Yahoos ( http://developer.yahoo.com/yui/theater/ ) video collections on technology & software.

I've got a question for you Ryan. When you decided to develop your app did you specifically try to be general in learning or focus in one specific area? The reason I ask is that the service can be made to cover all areas but at the risk of dilution in making what users want. The other extreme is you tailor you app to such a small market you don't get enough users.

How did you make this decision?
