Serena singing to raise awareness

As @arpie says, any publicity is good publicity. The cynic, of course, finds the timing interesting (WTF is a brand ambassador anyway) and the conversations I've heard about this seem peppered by "Oh, Serena can sing." Good for her. Nice publicity.

I believe people are precisely as aware as they chose to be. If you think it's helpful, that's excellent. It still give me the irrits :)
