I wrote my wiki server [1], as I was missing a proper freeware at that time. I run one instance at home for my private stuff and one on my office computer for confidential infos related to work.
The wiki stores pages in simple text files that are easy to backup, it automatically calculates birthdays of my contacts (stored with semantic annotation in an XML style), and provides an Android App to synchronize all pages on a mobile phone. Many wiki pages are organized hiararchically, but most times I use the full text search.
Technically it runs with Java on any OS, and has a built-in web server.
