  For a long time people made the mistake of thinking the proton was
understood. New experiments, ranging from form factors to deeply virtual
Compton scattering, promise a new era of highly informative studies. Among the
controversial topics of the future may be such basic features as the physical
size of the proton, the role of quark orbital angular momentum, and the
possibility of making "femto-photographic" images of hadronic micro-structure.
