Gabi Abramac (Sokrat Language Institute, Zagreb, Croatia) WHAT’S UP WITH WHATSAPP IN THE HAREDI WORLD? ABSTRACT This article examines the transformative effect that digital technologies are having in the contemporary Haredi society. Haredim are ultra-orthodox Jews who follow a devout lifestyle according to the collective body of Jewish religious laws, and they live in a self-imposed exclusion from the modern, secular world. Their leaders fiercely discourage the use of the Internet and smart phones. Nonetheless, as the Internet is recognized as a useful business tool, the use of filtered Internet access is approved. Hence, kosher Internet filters are advocated, and kosher phones are available for purchase. A significant number of Haredim have resorted to the use of WhatsApp smart phone messenger as an alternative to online social media networks, which they are supposed to completely avoid.
