Twitter, Facebook and YouTube. These are the most active social communities and allow journalists to gauge what people think of just about anything. I like to aggregate and incorporate relevant tweets in my articles to give people perspective. Using monitoring sites like Kurrently and Monitter are great for following the world's reaction to any topic.
