Abstract
For billions of people, the internet has become a second home. It is where we meet friends and strangers, where we organise and learn, debate, deceive, and do business. In some respects, it is like the town square it was once claimed to be, while in others, it provides a strange new mode of interaction whose influence on us we are yet to understand. This collection of papers aims to give a short indication of some of the exciting philosophical work being carried out at the moment that addresses the novel aspects of online communication. The topics range from the expressive functions of emoji to the oppressive powers of search engines.
