Yarn is great and speeds up npm install times drastically! However, within the first few hours of the official release yarn issues came pouring in to the tune of >380 today. What is the yarn team doing to address those issues quickly? Is there any timeline for releases?
Also, has there been any discussion around adding yarn's caching functionality or parallel install into npm core? What do you see as the future of yarn and npm? Thank you!
Why build a new system rather than push for changes in npm itself? There's plenty of speculation out there, but perhaps you could talk about how Yarn got started; or generally how that kind of decision plays out at facebook? (that is - ramping up an open source project of this scope and potential scale is not a trivial undertaking, how did you decide it was the right way forward?)
