Federated Ecology: Steps Toward Confederated Intelligence

Welcome to the second issue of IEEE Transactions on Computational Social Systems (TCSS) this year. First, I am grateful to report that, as of February 7, 2021, the Citescore of TCSS has leapfrogged back to 5.8, a new high, which indicates the high quality and relevance of IEEE TCSS in the field of social computing and computational social systems research. Many thanks to all of you for your great effort and support.
