It's a day of keynotes today, but for the last one we're back in the smaller WikiSym 2007 setting, for a talk by the inventor of the wiki, Ward Cunningham. He is also a pioneer in software design patterns research (the field for whose uses he invented the wiki, of course), and in what's called agile software development, however. He begins by noting that wikis are ultimately an exercise in simplicity - focussing on some very simple processes upon which large structures such as Wikipedia can be built.
