Shawn, go for it. It is highly recommended by many people who are successful in social media. Post links to the video blog in your regular blog, on facebook, here, linkedin, twitter, google+, wherever you are signed up and put as many tags on it as you can. The search potential is huge. I haven’t started yet, but have been thinking about how to get myself set up. Hopefully I will have everything ready to go by mid-January.
