Are there **ANY** YA short fiction markets? Other than targeted (and probably invitation-only) anthologies?

As far as I can tell, the only vibrant short fiction market that is actually alive in America today is SF & F. I bless the gods that let it prosper - while cursing the fact that, as a result, few short fiction readers ever see anything we write, because it has Genre Cooties. No John Kessell or Theodora Goss for them, then!
