2007 U.S. Open already started on Aug. 27 until Sep. 9. I used to watch grand slam games, at least for semi-finals and finals. However, during the recent years (actually 3-4 years), I didn’t watch any of them and sometimes even missed the news recast. The top seeds in men and in women also have changed the faces.
This time, thanks to the special topic in New York Times, I did notice it. Some interactive features are quite interesting, e.g. “Beating Federer” (how do you beat Roger Feder at the U.S. Open?) and “The Master of Clay Takes Amin at the Fast Courts” (Rafael Nadal’s approach). Plus the amazing display of data over Serena Williams’s Professional Career.
