This seems totally out of left-field move that only provides PR for SurveyMonkey. And while that may be somewhat true, this decision actually makes more sense if you dive into Serena's more recent endeavors.

Aside from being one of the world's greatest tennis players, she is clearly an accomplished business woman. She has started her own clothing line, owns a portion of the Miami Dolphins, and has started several successful charities. Most importantly, she knows how to market herself really really well.

Board members don't always have to have directly related experience to the companies they advise. A progressive company like SurveyMonkey that puts a lot of effort into supporting charities and positive social changes could really use the insight of someone like Serena.
