  The initial results of microlensing surveys toward the Galactic bulge and the
LMC are puzzling. Toward the LMC, the total mass in MACHOs is of order half
that required to explain the dark matter, but the estimated MACHO mass (~0.4
Msun) is most consistent with stars that should have been seen. Toward the
bulge, the total mass is consistent with that given by dynamical estimates of
the bulge mass, but the observed timescales seem to require that a large
fraction of the bulge is made of brown dwarfs. I discuss possible experiments
to resolve these puzzles. I also discuss several applications of microlensing
to non-dark-matter problems including searching for planets and imaging the
black hole at the center of a quasar with 10^{-10} arcsec resolution.
