A few quick first thoughts, having just flipped the switch. I think the description and website fields should be click to edit (and the labels need to be wired up). And I'm not a fan of the increasing emphasis on % LOC by programming language - this seems like an extremely low value metric to be so prominent, and a terrible way to distinguish between repos!

I'm looking forward to digging more into the redesign in my usage of it today. Glad to see GitHub continuing to improve and happy to re-think the current state of the app.
