Dmitri Baughman writes "I'm the IT guy at a small software development company of about 100 employees. Everyone is technically inclined, with disciplines in development, QA, and PM areas. As part of a monthly knowledge-sharing meeting, I've been asked to give a 30-minute presentation about our computing and networking infrastructure. I manage a pretty typical environment, so I'm not sure how to present the information in a fun and engaging way. I think network diagrams and bandwidth usage charts would make anyone's eyes glaze over! Any ideas for holding everyone's interest?"
