The conference was great inter-disciplinary fun, as it included statisticians, biotstatisticians, epidemiologists and even a few economists. I got to meet some famous people from other fields and also learned a lot (though there were a couple of presentations where simultaneous inter-disciplinary translation would have helped).
Two quotes that I liked well enough to write down:
"My colleagues, they study artificial intelligence; me, I study natural stupidity" - Amos Tversky
"Matching is an attempt to approximate what reweighting is doing directly" - Justin McCrary
In addition to providing the Tversky quote, Sander Greenland's keynote speech taught me the term "nullism", which indicates excessive reverence for the null hypothesis in classical hypothesis testing. I expect that term to come in handy in future.
