A short exploration of the business value of social media tools - inside and outside the wall. Presented to the AGM of the Australian Graduate School of Entrepreneurship (http://www.swinburne.edu.au/business/agse/) and for the product launch of IntranetManager.NET (http://www.elcom.com.au/Newsletters/IM-Launch/IM-Launch/default.aspx). It was just lucky that two groups asked me to present on essentially the same content on consecutive days. A transcript of the talk is available at http://www.acidlabs.org/2008/11/17/why-are-we-even-arguing-about-this/.
