10. Wiki-Dell • Customers helping customers is something that we encourage at Dell and wikis are one of the ways we're pursuing that goal. We will be launching our first customer-facing wiki later this month, … We'll be monitoring the wiki’s effectiveness closely as we determine how best to take advantage of this technology in other areas. We’ll use wiki technology internally to make our processes more efficient for our teams and we will continue to expand our internal wikis in the coming year. We are also looking at better leveraging the community knowledge in the Dell Community Forums to allow our customers to more easily find the solutions they need. We are considering the idea of creating individual wikis with the knowledge distilled from threads in forum conversations. • From Dell.com (4/19/07) • http://www.ideastorm.com/article/show/62156

18. The concept of scale-free networks

19. Scale-free networks • New nodes show affinity to attach to nodes that are already well connected • Six-degrees of separation! • Flow funneled through well connected nodes • Random networks fail gradually as nodes breakdown • Scale-free networks can show no break-downs if nodes breakdown randomly • However, targeted attacks breakdown scale-free networks quickly

20. Implications of Scale-free networks • Malicious viruses, DOS attacks targeted at a few central nodes can devastate Internet • Predatory hiring – focus on key individuals! • Epidemiology – stopping disease progression
