Mike Cannon-Brookes, Atlassian's co-Founder, recently presented on Organisational Wiki Adoption at WebDirections South 2007 in Sydney, Australia. The presentation is excellent on both content and design - in fact, Mike set a goal of no bullet points: "FYI I set myself the challenge of doing an entire 1 hour presentation with no bullet points - and succeeded! I was even running quite a bit over time so had to run through the last few slides very fast." That last sentence says it all - when you don't tie yourself to bullet points and rigid structure, you can more easily adjust your pace to fill - or finish in - the time allotted. Less structure = more flexibility = very wiki-like. All in all, an excellent piece, and well worth a few minutes of your time:
