Reputation is the opinion (more technically, a social evaluation) of the public toward a person, a group of people, or an organization. It is an important factor in many fields, such as education, business, online communities or social status.
Reputation is known to be a ubiquitous, spontaneous and highly efficient mechanism of social control in natural societies. It is a subject of study in social, management and technological sciences. Its influence ranges from competitive settings, like markets, to cooperative ones, like firms, organisations, institutions and communities. Furthermore, reputation acts on different levels of agency, individual and supra-individual. At the supra-individual level, it concerns groups, communities, collectives and abstract social entities (such as firms, corporations, organizations, countries, cultures and even civilizations). It affects phenomena of different scale, from everyday life to relationships between nations. Reputation is a fundamental instrument of social order, based upon distributed, spontaneous social control.
Note how I placed all my toons in my signature. I have an opinion. I will back it up until I am proven incorrect. At which time I will form a new opinion and repeat this procedure. In order to be held accountable for my opinions, I allow each and every individual to approach me as they please in order to discuss those opinions. The Karma system is in place for a reason, and flawed or not, those who's opinions ring true and who's humility allow them to be proven wrong without repercussion are shown through this system.
