From their Meetup.com page:
So I think it's time that Atlanta catches up with the rest of the innovative cities in this country and dive into the world of Node.
The focus of this group will be to learn node js through a practical approach. We will have keynote introductions of meetings, followed by discussions, and then hacking/development sessions where we will learn to rapidly build applications. While we may have the occasional outside expert speaker, our goals are to promote knowledge and gain experience in this new technology by work from members within the group.
And of course anyone interested in changing the world.
We will have a heavy focus on mobile computing devices and other smart devices like TVs with less focus on plain desktop pc.
