I'm really chuffed that Rafe and Ewan have decided to use Wiki technology for documention of OPL language and Symbian devices. Wikis are just great for this, simple to modify, easy to correct and annotate, and it's trivial to link together a whole web of pages.

The LOAF and FOAF social software projects make extensive use of Wikis, but some of the best examples of Wiki use I've seen are not computer related: Wikipedia, Wiktionary and the Open Guide to London are just superb resources.
