With the advent of the internet and even more so with the (not so) social media, we can observe that the public political arena has been differentiated into several distinct publics. This constitutes a working hypothesis in order to check whether there are necessary as well as sufficient evidence that there is a lack of exchange of opinions between the various publics. Technology is an intervening process which basically might be able to advance or hinder exchange between groups of society. Following the much debated theory of communicative action of Jürgen Habermas the existence of one public is a precondition of the theory. Empirical tests are needed more than ever.
