The fact is, you do not need to create traffic. It is already there. You just need to divert some of it your way.
When a police officer stands in the road to divert traffic around an accident, he isn't creating that traffic. He only diverts it to where he wants it to go.
Sometimes he automates the process by setting out flares in the road. The same thing applies to diverting web traffic. You can stand in the street pointing the way by going to Facebook and others every time you create a blog post, or you could automate part of the process. Using tools like the Facebook app Networked Blogs or sites like twitterfeed.com can help handle the task of updating your social media accounts.
This will free up your time to go grab traffic elsewhere.
