I do love EQUATIONS! Trust me I am an engineer! So I start to read this book looking for formulas! But Chris and Julien have that particular talent to write about complex things and translate it in such a way that you can actually make things happen.
Was I disapointed not finding tons of equations? Not really! Instead, It made me think of my actual web strategy and I implement changes right away!
Often, books like The Impact Equation suggests reflexions, excercices, etc. With The Impact Equation: I did them all! I even wrote IN THE BOOK with a pen! (I usually never do that)
Special thanks to Julien: "J'ai eu du fun à lire ce livre!"
So in the end, I recommend The Impact Equation! Because for your second book (after Trust Agents: Using the Web to Build Influence, Improve Reputation, and Earn Trust
), you deliver... again!
