Radiojornalismo comunitário em mídias sociais e microblogs: circulação de conteúdos publicados no portal RadioTube.

This paper seeks to investigate how radio journalism contents' circulation reconfigures itself in a period of consolidation of digital communications' platforms, such as social media and microblogging services, which support the construction of online and offline social networks. It starts with the premise that these platforms leverage not only commercial radios range but also community broadcasting. Particularly, it will analyze digital audio distribution and circulation strategies at the Brazilian collaborative portal Radiotube, that comprehends a network of over 1,400 communitary, commercial, and web radios from all over the country.
