History

The Serendipity project was started by Jannis Hermanns in the winter of 2002, then still called jBlog. Due to a naming conflict with an existing blog publishing system, Sterling Hughes suggested the name serendipity. This suggestion is based on an Essay by Sam Ruby.^[6] The short form s9y stems from abbreviations such as i18n for internationalization where the number represents the amount of omitted letters. Today the project is maintained by Garvin Hicking.
