As long as it's correct. :)
Heh. No entirely true... that's the point of the wiki: anyone in the WPMU community can change it to add a comment in the right place, anyone can rearrange it so it reads better, and anyone can create new topics that synthesize previously unconnected thoughts.
Once we have trained each other to use the wiki we collectively grow and garden topics, each able to make things just a "little better".
Its about realising that what you right doesn't have to be complete, just a little useful. And it matters little once everyone looking at it realises that it is a malleable form that is collaboratively shifted to reflect the consolidated conclusion of conversations.
Forums such as this, well, the lack of being able to "garden together" really shows up. This comment of mine, for instance, is buried under "WP_USE_MULTIPLE_DB" which is a response to your comment but nothing about the topic subject.
If this was on codex, any person who saw the comment could refactor the text such that it was in the most appropriate place.
Our current advice for newcomers is to "search", which is fine if that newcomer can 1) find the mu search box, 2) be bothered with the extra three clicks 3) know what to search for. Further, that newcomer has currently no opportunity to contribute by helping to restructure what was found other than by creating yet another forum posting.
A problem with all communities is the gap between the existing users and the new ones. Wikis help close that gap by ensuring the fidelity of the content and the meaningfulness of the link names. Fidelity is driven by collective gardening and right-place commenting and meaningfulness is driven from the URL space (slug, in WP terms).
Some examples of important topics that got lost:
