This GraphConnect 2013 talk by FiftyThree's Aseem Kishore does talk a little about how Neo4j stores data internally as linked lists, when discussing how to best model your data: https://vimeo.com/79390659
It was recorded eight months ago, but I only just discovered and thought that it was thought provoking in general, even if some of the lessons learnt were quite basic. I would love to see more "post mortems" like this.
