Harold, Great post. I'm doing my research on informal learnning in virtual communities of professionals (case study tourism profesisonals)using online social media. Here are my answers to your questions: How do I keep track of all of this information? Casuistic and random activity of network members fosters casual innovation. Connective learning practices by Siemens and Downes are open and flexible to foster this casuality How do I make sense of changing conditions and new knowledge? Social intelligence exists and lets knowledge leaders identify critical knowledge How can I develop and improve critical thinking skills? Practice spreads new culture of sharing knowledge. Need to discriminate critical knowledge fosters critical thinking skills How can we cooperate? Cooperation is human characteristic. Social networks build their own cooperation rules. How can I collaborate better? Improving collaboration is also consequence of practicing and of essential values: trust, confidence, cohesion, sense making, and openness How can I engage in problem-solving activities at the edge of my expertise? Just, sharing it with others and letting them feel part of your project. This are mu insights. Hope you find any sense iin it. Regards, Oriol
