That would work, and make a collaborative effort possible on an ongoing basis, rather than a one-off before putting up the new page.

When I say "the About page", what I really mean is "whatever page the rightmost link in the top navigation bar of LessWrong points to". I notice this is already an indirect link, via an URL which redirects to an early post of Eliezer's, so I assume making it point to the Wiki instead is a matter of changing a config file somewhere.
