Optically thin thermal emission may be a viable alternative to optically thick accretion disks for the origin of the optical/UV Big Blue Bump. In this contribution I summarize a number of points favoring the optically thin, or free-free, hypothesis. The free-free model is consistent with the most stringent quasar size and luminosity constraints provided sources are composed of a large number of very small and dense cloudlets or filaments.
