Lesson 2 is broken on GitHub

I apologize in advance if this is the wrong place to post this. But currently Lesson 2 in GitHub is broken as of the last two commits. I see issues have been placed in GitHub a few days ago. It is probably a very simple fix to correct the broken JSON format, But currently if people follow the fast.ai recommendation of pulling latest from GitHub (and they are new to this in general) they will experience a broken notebook.
