Well, linkbait, basically writing really creating interesting stories that will result in other blogs linking to you, and getting voted on at social media sites like digg, netscape, etcand it  is quite the artform. Andy Hagan has a guide to creating linkbait here, the section on promotion is quite good. My two favourite bloggers who I believe are quite good at the art of linkbaiting are Shoemoney and John Chow. Both those bloggers whilst not full time bloggers, they do work on the internet as a full time activity, and are definitely worth checking out.
