This post is about my thoughts on the Triangulation Chapter 239, where Ward Cunningham is interviewed. He is the inventor of the wiki, he contributed to the development of Eclipse and Relic and is part of the Smalltalk community.
Wikis are the biggest knowledge source in the world, where anyone can write, read and edit any publication. Extreme Programming is a methodology for agile software development where there is more emphasis in adaptability than predictability.
The interview showed me how a simple man can make a huge contribution to humanity, such as wikis; where people share their knowledge just to make that knowledge public for everyone, and how we can work together for a better society.
