Nowadays, end-users’ environment is plenty of services that support their life style, and involving them in the process of service creation can allows them to benefit from a cheaper, faster, and better service provisioning. There are already tools targeted to the authoring and
consumption of services. However these tools consider end-users as isolated individuals, missing the potential that their social environment can bring to them. In this paper, we investigate how social networks can be used to improve the authoring and consumption of services by end-users. We propose a social network of service compositions as a valuable
mechanism to share knowledge among end-users in order to improve their skills in composing new services. In addition, we analyse the underlying relationships created among service compositions in order to provide end-users with an intuitive way of browsing them.
