JuliaCon's been in the works for a while now. I'm helping organize it, feel free to leave any questions here and I'll try to give you a prompt response.

It would be great for the people that cannot fly to the US if you stream online the talks

We'll definitely record the talks and post them online -- but whether we'll have live-streaming is TBD.

I am certainly excited. I think this will be a fantastic event.
