Social Internet of Things are changing what social patterns can be, and will bring unprecedented online and offline social experiences. Social cloud is an improvement over social network in order to cooperatively provide computing facilities through social interactions. Both of these two field needs more research efforts to have a generic or unified supporting architecture, in order to integrate with various involved technologies. These two paradigms are both related to Social Networks, Cloud Computing, and Internet of Things. Therefore, we have reasons to believe that they have many potentials to support each other, and we predict that the two will be merged in one way or another.
