Great communicators can influence change, whether political, cultural or in business. From Winston Churchill to Ronald Reagan, Steve Jobs to Martin Luther King, history is full of individuals who, through their words and deeds, have shifted public opinion and behavior. Barack Obama, Stephen Colbert, and the “Oracle of Omaha” Warren Buffet are all hailed as great communicators – no argument here. President Obama’s communication abilities are absolutely phenomenal. Mr. Colbert, through humor and wit, scores political points and creates cultural references (“Truthiness” anyone?) that resonate with legions of fans. And of course, it’s not just the financial public that eagerly anticipates Warren Buffet’s yearly shareholder letter – Main Street does too.
