This book looks at what our pronoun usage in our language says about us. There is also an online website which uses the same tools Pennebaker uses in his studies, providing the reader with an interactive aspect as well. The concepts in the book about how different pronouns correlate with different social status, group dynamics, gender, and other factors provide an insight on an aspect of daily life most people never think about. It also includes charts and graphs to help convey information, although Pennebaker does not provide his raw data for portions of the book, only his conclusion. By the end of the book many points he makes feel repetitive, making the later chapters less interesting to read.
