    Nick is a good speaker, thanks for the presentation. Some of the objects, like Preparables, remind me of J2EE patterns like Data Transfer Objects, although I'm sure these patterns are also in the GOF book. Interesting to see their implementation at facebook, and the unique constraints and requirements they face due to the, (in best Carl Sagan impression) "billions and billions" of page views.

    Well if I understand correctly there is a succinct difference. The multi-pass framework is specifically designed to make use of multi-get capabilities of key-value stores. The multiple 'components' of a webpage can request data from their memcache layer in parallel over the same data request. I think this is quit original. There are frameworks that allow multiple page components to render in parallel with multi threading. But there is no other framework that allows multiple page components retrieve data in paralel.
