[IPython-dev] Launching Jupyter Notebook Sharing on Quantopian

[Fernando Perez]

This is awesome, Scott! Absolutely thrilled to see this...

As we look at the integration of Fabian's gallery with nbviewer (as per
last week's meeting), we should definitely follow with this kind of tool...

Thanks for sharing this, great job by you and the whole Quantopian team!

Cheers
