[Update: I've updated this article and put it on my personal website here.]
At the same time I was looking for somewhere to share my experiences earthquake-proofing a wine cellar, I ran across Wired's How-to Wiki. So I wrote an articles on how to earthquake proof a wine cellar. Of course, there's no such thing as earthquake proof, but our wine cellar is certainly more earthquake resistant than it was before.
Wired's How-to wiki seems to be off to a slow start, but there are some useful articles in there, mixed in with bar bets and other cruft.
