At some point, when you become famous enough (or infamous, in Parker's case), things like extravagant weddings are going to get attention from the media, whether you like it or not. I would not be entirely surprised if Zuckerberg took this into consideration when he planned his surprise, low-key backyard wedding. In the wake of the great recession, which most of America is still slowly recovering from, fancy cars and nice suits aren't going to win you sympathy from the American public. If you care about the public's perception of you, then adopting a low-key lifestyle would be a prudent effort in managing that. If you don't care, then feel free to live extravagantly, and be prepared to either tune out the blogs and trolls, or have some thick skin and learn to deal with them.
