I know that some people like it...but a lot of us hate it. If I want to create a link, I can use brackets. I would prefer that not every CamelCase word gets made into a link. To me a link implies intention to create, whereas auto CamelCase link generation can pepper docs (depending on what you're writing) with links that lead nowhere.
The Trunk docs themselves have several references to WikiWord that go nowhere
Perhaps there could be an option to ignore auto CamelCase link generation. If set to On, then only manually entered links (with [[ ]] brackets) would be made into links. That way people would have the choice and could set up their personal wikis however they liked. I would like that very much.
Otherwise, brilliant, good show, keep fighting the good fight, rock on, etc.!
