Rather than just showing you a list of social networks, Pocket also shows you people. It makes the experience much more human, rather than the typical dry list of services. This feels like a next-generation interface.
The UI is well done too; the distinction between services and people is made very clear by the iconography. Services are represented by white icons in rounded rect’s, whereas people are depicted by circular-masked profile pictures. The effect is subtle, but has a profound effect in use.
