I have added the Tab Slideshow to Firefox https://addons.mozilla.org/en-US/firefox/addon/2688 and have it runnning full screen on a laptop next to my trading computer. It goes through a list of news sites every 15 seconds. What are the best news sites? I have wsj.com, bloomberg.com, ft.com, dealbreaker.com. What other sites have news and rumour quick?
