yesterday's announcement, There has been time to think. Google showed a real interest in Wikidata. It created a new tool to help improve the quality of its data. But the real expertise of Google is in determining the probability of facts. It is part and parcel of its ranking algorithms.
It would be as awesome when Google would indicate those statements it deems to have a less than even chance of being true. The combination of such a list and the new tool would make the efforts of the people seeking sources all the more relevant. When statements are debunked, it has a potential quality effect to all the associated Wikimedia projects. Given that it is probable that most statements are fine, it makes for more concentrated effort and consequently its effects will be noticed.
While we are on this line of thought, given the data of Freebase, Google could indicate based on its algorithms how probable its sets of data are. Everything that is highly likely should be a candidate for import in Wikidata. The other reason for importing data into Wikidata anyway is that it is an invitation to all the Freebasers to join our ranks, increase our expertise and together be awesome.
