It's definitely helped my writing -- just from the sheer amount of text I write on here. I've become an awful lot better at writing clearly and persuasively, organising my thoughts, and conveying meaning. That's helped me a lot at work, actually, especially during performance reviews and interviews. It also helps me to anticipate possible responses, and pre-emptively discuss them so that I'm in control of the conversation. That allows me, at work, to make sure that my ideas are the ones that are taken the most seriously, because I've demonstrated that I've thought about it from all angles already. Finally, writing on CFC has taught me how to speak in a more authoritative, leader-like tone. My mode of speech at work has changed from being combative to authoritative, and that's largely because of the practice I got on CFC, from avoiding confrontational arguments and seeking out more genuine discussions with "thought leaders".
