In a recent post, Beth Kanter in her keynote: Nonprofits in the Age of Social Networks, has provided her slideshow for her keynote and the notes. Additionally, a wiki which holds notes for the conference is also provided.
Because I often struggle to articulate Web 2.0 tools and concepts, I find resources like these helpful. In particular, Holly Ross' keynote, Lose Control: Why and How Web 2.0 Matters to Nonprofits is an interesting way of presenting Web 2.0.
Have fun investigating these resources!
