Today, social media is the glue that binds together the internet's content, especially as it emerges. As a content creator, it's your job to reach out to users in social media. If you can accomplish that, you might be asking, what's next?
Complete the cycle: Get users working for you by making it easy for them to share your content using social media. That way, they can do what they like doing best: investigating something interesting that one of their friends shares with them, adding to whatever conversation is going on about it, and re-distributing it in their own way.
If you can make your content part of the cycle, you'll not only notice that it gets spread around, drawing traffic. It also gets re-contextualized and delivered in ways that delight marketers and their audience.
