We summarize three alternative extensions of the quark-valence picture of nucleon strangeness and spin, including (1) gluon spin in QCD, (2) Bjorken sum rule and QCD, (3) D--E meson mixing and tadpole leakage. All three approaches suggest that ~40% of the nucleon's spin (as well as its momentum) resides with quarks, but that less than 6% is due to strange quarks.
