The use of Twitter, a well known microblogging service, spreads around the library 2.0 community in Germany. Several colleagues and libraries and even organizations are twittering about their work and leisure. So, if you are curious, what german librarians have to say in short, you can find an overview (still growing) at a page of LIS Wiki. Even a librarian association, the Berufsverband Information Bibliothek, has a twitter account.
