I have been blogging for a couple years and even decided to create another blog about blogging - titled MoreIncomeBlogging....
Anyhow, I think creating good content, interacting with your audience, etc is a start. You will slowly build relationships, but it will pay off in the long run if you are honest and helpful. Forums, commenting on other blogs, etc. It is important to add value, be sincere, and not overly promotional - this is true in social media as well! Good luck!
