Ward mentions an important feature of wikis: Fragility
"articles added to a wiki are at the editorial mercy of the wiki's other participants"
The article says: "The positive spin on the fragility of a wiki though, is that any flames or spam can be immediately removed so that wikis imbue good participants with a kind of survival-of-the-fittest power. "You need to generate real content," says one wiki source on the Web. "Anything else will be removed. So anyone can play, but only good players last."
