As many here have answered, you don't need a graduate degree to get into this field and make money. Both myself and my partner at Repustate (http://www.repustate.com http://www.repustate.com) have undergrads in CS, but other than that, we just read a lot of published papers from well known experts in the field, like Bo Pang @ Yahoo. She's a great source of information if you're interested in SVMs (support vector machines) and contextual polarity, that kind of stuff. Generally speaking, Cornell University has a really strong library of research in this area.
