Abstract
I review several central open questions concerning GRB Jets: i) I discuss a new estimate of the beaming correction for the rate of GRBs ∼ 75±20; ii) I discuss the universal structured jet (USJ) model and conclude that while jets might be structured they are less likely to be universal; iii) I discuss recent observations of a sideways expansion of a GRB afterglow and compare these with current hydrodynamics simulations of jet evolution; iv) I discuss the implications of resent outliers to the energy-angle relation.
