We prove that an random matrix with independent entries is completely delocalized. Suppose that the entries of have zero means, variances uniformly bounded below, and a uniform tail decay of exponential type. Then with high probability all unit eigenvectors of have all coordinates of magnitude , modulo logarithmic corrections. This comes as a consequence of a new, geometric approach to delocalization for random matrices.
