If you are interested in hearing some of the sessions from Northern Voice, I suggest you check out northernvoice.podcastspot.com as it contains audio recordings of nearly every session from both MooseCamp and Northern Voice.
The sessions have titles like “Using Video to Change the World”, “The Social Web for Karmic Good”, “Legal Rights and Liabilities for Bloggers” and of course “Why Do We Blog?”.
There is a fair bit of content posted on there, so if you have some free time, check them out.
