Google Voice
Google Voice. The help content for Google Voice is pretty cool — just a list of basic tasks (about 20) with short instructional video clips. I don’t know why the scripts to the video tutorials aren’t made available, but it’s a good example of how to do video tutorials for help content. Usually Google knows what it’s doing, too.
It would also be useful to navigate from one help topic to another without having to close the video screen upon the ending of one topic only to have it open again for the next topic.
Perhaps a video screen embedded on the page is all that’s needed to achieve this.
That said, the instructional videos clips excellent.
