From their Meetup page:
PyData-Atlanta is interested in telling insightful stories about data and exploring the methods behind those stories. We advocate for open data ecosystems and workflows that center on open source tools, especially (but not exclusively) based in Python. We are focused on the vertical integration of tools and skills that transform raw data into insights, and we aim to provide a seminar-like learning environment. We host short interactive presentations, audience-contributed lightning talks, panel discussions, and informal networking opportunities. Our events can benefit both experienced and beginner data scientists alike.
Announced in the September 2016 meeting, this meetup is already the 6th largest PyData meetup in the world. Way to go!
