The new WFC3/IR camera aboard HST enables us to survey the sky in the near-IR data 40x more efficiently than ever before -- permitting us to make enormous strides in our searches for z>=7 galaxies. Already in the 15 months of observations, we have deep and ultra-deep observation over 52+ arcmin**2 over legacy fields like the HUDF and GOODS. With these data, we have been able to select 80+ z 7 galaxies, 50+ z 8 galaxies, and even a candidate z 10 galaxy. These new selections have allowed us to quantify the evolution of the UV LF and
faint-end slope from z 10, significantly constrain the stellar populations and dust properties of z 7-10 galaxies, and construct a general picture of how galaxies build up early in the universe. In this presentation, I highlight a few of our results.
