Video helps immensely. I'd say not to necessarily stay on one video sharing site or channel, as some traffic simply doesn't cross.
- Do any of you have experiences with free online video publishing with resources like currenttv.com or youtube.com?
YouTube is not bad if I want to show a quick clip of something I did or speak directly to the camera - it's more slanted towards consumer community, where some others have b2b segments. I find klip.tv has an excellent tool, VideoJug.com does an excellent job of giving you a multimedia channel of your content, that is also viral, and incorporates trackback for those who syndicate you. Then there's splashcastmedia.com which has a similiar, sleeker service that is more like a blog. If you're going to do a full-blown show with weekly updates, blip.tv is good.
- Are you using this type of media to promote yourself online or your content?
Yes.
- How do you use it to drive traffic back to your website, or produce business?
On some platforms like klip.tv, you can embed your URL in the player, and you can embed the entire player into your site. On YouTube, I briefly show my link before and after and it shows up in the description when you use the http:// prefix, people click on that and visit you at times. I like to send them to a specific URL where they can pick up more info.
Hope this helps!
