Last week Jim Gray was declared missing, after he didn't returned on a solo sailing trip, and yesterday the Coast Guard suspended it's searches.
You can now help find Jim Gray (if you use a database of any sort (who doesn't) you OWE a lot to this man), by analysing satellite images. You are presented with 5 satellite pictures and you classify them (nothing interesting/is boat may be in there) all images classified with a possibility will be carefully examined by specialists.
It's a very brilliant idea, using the power of thousands of human who can easily reject the negative images, and let the experts concentrate on the images that may show the boat not wasting time on the negatives.
You can help, by classifying pictures using by accepting this task on amazon's Mechanical Turk.
Werners Vogels not only explains it much better than me, but it also has details how the whole process has been assembled.
[Update 4 feb: Private search initiative is being coordinated through this blog]
