A "maven" is a person who is an expert or knowledgeable in a particular field. This term often refers to someone who shares their insights and expertise with others, helping them understand complex topics. Maven can be found in various areas, such as technology, fashion, or finance, where they influence trends and decisions. The concept of a maven is closely associated with the idea of a connector and a salesperson, as described in Malcolm Gladwell's book, "The Tipping Point." Together, these roles help spread information and ideas, making maven a key player in social networks and communities.
