Cunningham first developed the ability to automatically create internal links (read: new notes) when typing text in CamelCase. This meant you could easily be typing a sentence while describing a piece of information and simply type a word (or series of words) in CamelCase which would create a link to another piece of information (even if its page hadn’t already been created).This was quickly superseded by the double square bracket links most wiki’s use today to achieve the same results, and its the staple creation method in both wiki’s and other premier information systems today.
