Quantopian is aiming to switch over to Airflow over the course of this year, replacing our existing systems for ingesting financial data. I'll be at SREcon Americas this year, potentially with some of my coworkers; we're located in Boston, which doesn't seem to have many users yet, so we'd love to get to know some other users while we're on the west coast!
It looks like we'll be missing the next Bay Area meetup, but perhaps some Airflow users will also be at SREcon? -James M.
