  I review and update ideas about the quantum theory of de Sitter space. New
results include a quantum relation between energy and entropy of states in the
causal patch, which is satisfied by small dS black holes. I also discuss the
preliminaries of a quantum theory in global coordinates, which is invariant
under a q-deformed version of the de Sitter supergroup. In this context I
outline an algebraic derivation of the CSB scaling relation between Poincare
SUSY breaking and the dS radius. I also review recent work on infra-red
divergences in dS/CFT, as well as the phenomenology of CSB. I show that a
coincidence been two scales in the phenomenological model is explained by
insisting on the existence of galaxies.
