I'm not sure why Gawker wants to pick a fight in public against a chess master with a Stanford JD with huge cache of ammunition in the form of cash.
Gawker did it in the name of free speech by digging up privacy and slandering? Unfortunately being a digital gossip site does not mean it will be exempt from being sued like traditional gossip media such as national enquirer.
And both ancient and modern law codes are on the side of privacy against slandering, rather than on the side of abusing media power in the name of free speech, dated all the way back to the Code of Hammurabi. And suing Gawker is like an high ROI of no-brainer and an act of public service as there are so many precedents of like Hulk Hogan's case.
