Social media starter videos

I have just created a short series of videos aimed at absolute social media beginners. The first 4 videos in the collection walk you slowly through creating a Google account, using Google reader to subscribe to rss feeds and share content with friends, set up iGoogle as an information and social media web portal and creating a Twitter account.
I will be adding more to this series as time permits.
They are very slow paced and probably far too basic for the reasonably tech-savvy, but do feel free to point any of your less knowledgeable friends and colleagues towards them if you think they might be of some use.

They can all be found on my YouTube Channel or on the sidebar here.
