Video blogging???

My husband came back from shopping (for wood, mind you) and thought he came up with a great, innovative idea to help me market my book: video blogging. I don't know much about it, but I can only assume it would be me sitting in front of a web cam speaking about the same things I write in this blog. Generally, I don't consider myself a public speaker. That's more his thing. But perhaps I could verbalize what I feel passionate about, which is writing and all of its elements. I don't know. It's something to consider I guess.
