In case that didn't make sense to you, it's a reference to: http://steveblank.com/2009/12/21/the-elves-leave-middle-eart...

I think it's more likely to be a reference to Lord of the Rings. There's no need for the Steve Blank sub-reference for that statement to make sense.

He left Rivendell, sure, but maybe he's just moving to Lothlórien.
