Adoption of social media platforms by Swiss towns and cities remains timid for the moment. Facebook has by far the greatest success, doubtless because it was the first platform available and because its format lends itself well to public communication. Surprisingly, Twitter is used far less, although its format also is well-suited to certain communication needs of cities. Even in cases where a platform is adopted, the low number of followers and/or an absence of activity by the city point to limited enthusiasm for this new communication standard. However, a constant increase can be observed in the number of users of the main platforms, as in the average number of platforms used by towns and cities. This rather slow rate of adoption raises as many questions about the way in which cities communicate as about the usefulness of exploiting these new platforms.
