This was actually the first year the interactive component was put into NXNE (something I got to be a part of, as a NXNE Conference Volunteer this year) up here in Toronto, which replicates the interactive component of South by Southwest (SXSWi) held every March down south in Austin, Texas.
As luck shall have it, I found a link to the unofficial SXSW presentations channel. It's a place to share and find presentations from SXSW. Not only does it include 2010, but also previous years.
