You think FB doesn't consider durability and consistency essential? With almost one billion users?!

Wow.

Whether it is consequential or not is completely beside the point. As is whether you understand the "social graph".

Eventual consistency, yes. What I'm saying is if a few pics disappear for a half hour while things resolve themselves, nobody is going to care... or likely notice.

It's not a bank.

By the way, I believe social networking is mostly bullshit, which is my "LOL" at the "social graph".

Eventual consistency however provides no guarantee of consistency unless it is backed by absolute local consistency on every node. Don't you run into CAP theorem problems otherwise?
