Yes. Start with our lord and savious @zerohedge and go from there. He has a bunch of twitter accounts in his follow list. If zerohedge follows someone, they're generally either important to the news, or they're tweeting about the market every day. You can cull his list and find the gems pretty easily. From there, the list will grow as your interest in the markets grows. Twitter is pretty good about exposing you to the people followed by the people you follow. Easy to expand the network.
