Bliki: Expansion Joints

Martin Fowler details his 'Expansion Joints' technique for public speaking, which involves pre-planning optional topics that can be covered quickly or in detail. This method allows a speaker to adapt their talk's length on the fly, ensuring they finish on time without the audience noticing any adjustments. He explains using single flex-slides or skippable slide sequences to achieve this, a strategy that boosted his confidence, especially since he did not rehearse.
