Until Google decides to close it a few years from now in order to focus on what matters.
Federation of this data is the most important aspect of it, because people use many different sources for news and information, and should not have to search for every possible database of missing persons to find the information they need. For example, after the 2010 Haitian Earthquake, CNN, the New York Times, the Miami Herald, and the Google Person Finder all shared data[3] so that if any one (or several) went down, all that information was still available from other sources.
In any case, I don't know if you were trying to score free internet points or just being snarky, but it's generally a good idea to do basic research before repeating non sequiturs.

Kudos for donating money, but they announced a big contest, got tons of input and made this seem like a big focus, and then when that toy wasn't fun to play with anymore they ignored it for a few years until somebody remembered they had money to give away.
