I recently found this quite a useful page on INC.com. It provides a list of some of the most popular leadership and management experts in the world. The purpose of their work was to find out which people are globally the most popular management and leadership writers, in the English language. It takes into account measures like the number of Twitter followers, Goodreads ratings, Blog reputation etc. to build the list. It is comprehensive enough to provide the list from 51-100 experts as well. It has names like Jack Welch, Guy Kawasaki, Seth Godin etc.
If you see people in the list on this page you don’t recognize or aren’t following, check them out. Life is about constant learning. We’re all a product of our influences, so it only makes sense to improve both the quantity and more importantly, the quality of the people we listen to.
