One of the powerful things about a Wiki is the ability to collaboratively generate well structured and linked articles. If I make a statement that references another important idea, I can simply enclose that phrase in double square brackets and that phrase will be displayed as a link.
If you click on the link and that word or phrase does not yet exist as a wiki article, the wiki engine will propose that you create a new wiki page.
So, if you have an idea that's important, make it into a link using the double square bracket convention and either make a 'target' page, or leave it for the community. Wiki's make this easy, so give it a try.
