Update: Google GIS Tidbits - 6/17/11
A source close to Google says that Google has changed how it processes location requests, thus limited the sharing of locations of mobile devices. CNET reported on such sharing earlier in June. Exactly what has changed is not clear, but CNET reports it's seen a change.
Out of approximately 3,000 MAC addresses that CNET tested over the last few days, not one delivered a location from Google's database. Before June 15, Google's database showed them as appearing in locations as varied as [the U.S., China].

C|net reports that Google and Skyhook are collecting and making public unique IDs (MAC addresses) and physical addresses of some cell phones and other devices.
Tests performed over the last week by CNET and security researcher Ashkan Soltani showed that approximately 10 percent of laptops and mobile phones using Wi-Fi appear to be listed by Google as corresponding to street addresses. Skyhook Wireless' list of matches appears to be closer to 5 percent.
Google has added a new feature to Google Maps that lets users quickly access locations they rated, starred, or saved in Google Maps. However, those who don't use this feature with care may accidentally be sharing personal information.
The new feature, a tab for your favorite places is public by default and was launched via the Lat Long Blog.
