Hey ABCellars, great suggestions. Some of the things you suggest need some code changes on our part, and some we can all start solving right away.
Troubleshooting pages are easy to write and add to. If a water damage troubleshooting is specific to a device, then you should improve / create the device-specific troubleshooting page. Example.
But a lot of these questions can be solved by general water damage troubleshooting information. So let's make a really good page that explains all the options, and link everyone to that! [http://www.ifixit.com/Wiki/Electronics_Water_Damage|I just started a page]. Let's all pitch in and make it the top place on the internet to learn what to do when you have water damage.
If there is a specific procedure (like cleaning dried salt water from a circuit board), then we should take photos and make a guide, then link it from that page.
We have a plan for dealing with the old 'unanswered' questions, because I completely agree with you that they aren't relevant. We're a ways out from a solution on that because it's requiring a while to code, but we'll get there, I promise.
A good way to start on the [http://www.ifixit.com/Wiki/Electronics_Water_Damage|water damage] page would be to search through Answers for the top-rated water damage solutions and reformat them for a long-term article. Post here as you make progress, and I'll chime in with formatting help.
