The prehistory of the Gravatar: The Avatar
Bevor wir uns mit dem Gravatar beschäftigen, ist es gut zu wissen, was ein Avatar ist. Der Avatar ist eine statische oder dynamische, grafische Nutzerdarstellung. Der Avatar wird zur Identifikation einer Person im virtuellen Raum (Internet) genutzt. Die Kombination von Namen und Avatar führen dazu, dass man sich besser an eine virtuelle Person erinnern kann. Der Ursprung der Avatare findet sich in der Gamer-Szene im Internet, in welcher Internet-User durch auffällige Avatare wiedererkannt werden wollten. Mit dem Bloggen wurden die Avatare langsam erwachsen. Blogger legten sich auffällige Avatare zu oder machten einfach ein einprägsames Foto, welches sie als Avatar benutzten, denn bei der Vielfalt im Internet ist der Wiedererkennungswert wichtig. Das Problem war, dass man nun bei jedem Blog, jeder Social Community und jeder Website immer wieder sein Bild hochladen musste. Das ist ziemlich lästig und hier kommt der Gravatar ins Spiel.
Conclusion
Gravatar is a very useful tool to give users a consistent presence online. It is a free service that allows users to use avatar images on different websites. It makes it easy for users to log in through their avatar image and gives them a consistent presence. However, it is important that users are careful otherwise they can be identified as spammers.
