I could not enter "September 23rd 2015"; I had to enter 09 23 2015 (with the spaces, not slashes). Same with Sept. 11 -- 09 11 2001. I tried to see if this was somehow related to dates and date-based research. I entered 10 06 1973 (Oct. 6, 1973, the date the Yom Kippur War started), and I got sent to D. C. United -- the Major League Soccer site at RFK Stadium in Washington, D.C. Clearly something else is going on here. I strongly suspect that it has something to do with "geo tagging", which is how you're able to create a unique "tag" for your favorite locations.
