All wiki page titles are automatically linked anywhere within the wiki. So a page title of 'java' will cause any word 'java' to automatically become a link to the Java page. Very nice.

Well SnipSnap has a similar feature which is \[page_name_here] will link to a  page called page_name_here within the wiki. In my opinion this is more practical, because the user explicitly shows that he - or she - wants to link to a page. 
Making a rule where: "X word is automatically linked if exists a page named X" seems to me a bit harsh. But I never used such feature in any wiki. It might improve user experience, but not really sure about that...\\
What about if I don't want a certain word actually linking to a page within the wiki? Is that possible also?

As a user do you find such feature actually useful? 

Thanks for your input, hope to ear more from you soon.
Best Regards,
