Guy Kawasaki (not to be confused with Robert Kiyosaki) has a great post about The Nine Best Story Lines for Marketing which is based on Lois Kelly's Beyond Buzz: The Next Generation of of Word-of-Mouth Marketing. Of course the "best story lines" I think doesn't just apply to marketing but to blog writing too (some of which are actual vehicles for marketing).
For example, a lot of my essays usually follow the fourth example:
Except I really am arrogant in my posts. Most blog entries will probably fall under the sixth:
Contrarian/counterintuitive/challenging assumptions. These three themes are like first cousins, similar in many ways but slightly different. Contrarian perspectives defy conventional wisdom; they are positions that often are not in line with—or may even be directly opposite to—the wisdom of the crowd. The boldness of contrarian views grabs attention; the more original and less arrogant they are, the more useful they will be in provoking meaningful conversations.
Counterintuitive ideas fight with what our intuition (as opposed to a majority of the public) says is true. When you introduce counterintuitive ideas, it takes people a minute to reconcile the objective truth with their gut assumption about the topic. Framing views counter to how we intuitively think about topics—going against natural “gut instincts”—pauses and then resets how we think and talk about concepts.
Challenging widely-held assumptions means that when everyone else says the reason for an event is X, you show that it’s actually Y. Challenging assumptions is good for debate and discussion, and especially important in protecting corporate reputation.
Personalities and personal stories. There’s nothing more interesting than a personal story with some life lessons to help us understand what makes executives tick and what they value the most. The points of these personal stories are remembered, retold, and instilled into organizational culture. Robert Goizueta, the respected CEO of Coca-Cola, said he hated giving speeches but he was always telling stories—often personal ones about how he and his family had to flee Cuba when Castro took control and had nothing more than his education.
Similarly, when Steve Jobs gave the commencement address to Stanford University in June 2005, he shared his personal story and life lessons. That commencement address, “Stay Hungry. Stay Foolish,” was talked about on thousands of blog and was published verbatim in Fortune magazine. It helped us see Jobs in a new light.
