Kara Swisher is one of the lead writers and co-founders behind the Wall Street Journal's online publication All Things Digital, one of the Internet's speediest sites for breaking technology and start-up news. In addition to reporting on device release-date announcements and company mergers, she's a great source for the best tech-industry gossip. She broke the stories that Groupon president and COO Rob Solomon had left the company and that Flixter and Rotten Tomatoes were in acquisition talks with Yahoo! (and possibly Disney). When this woman reports a rumor, you can pretty much count on it to be true.
