Where is public communication of science going?

We have published this issue of JCOM while the call for papers is open for the twelfth Public Communication of Science and Technology conference. The biennial meeting will be held in April 2012 and for the first time in Italy: the hosting city in Florence. The 2012 edition of the PCST conference is being held after more than twenty years of growth of the network of scholars that founded it and the expansion of its boundaries outside the European context from which it was created. JCOM is a part of this network, made up not only of individuals but also of organisations, university departments, journals, national conferences and so on.
