Ok, so I very rarely do Facebook, but my wife does and so do a very considerable number of people. I don't hear any complaints about the usual scalability issues (speed and availability) I also don't see any evidence of Stonebraker's superior technology powering multi-million concurrent user applications. So frankly his claims seem absurd.

For the RSS feeds and for adding to your friends list, they may not need acid properties. they may be able to live with dirty reads on this to get it to scale. if you have not finished with the commit in a de-friends does it really matter if someone sees it as done when you have this level of volume? I actually agree with the guy that in many cases unstructured data like images and videos can often be stored outside of a database and this reduces over.
that being said. it sure sounds like the facebook guys don't know anything about sql or data modelling. its probably just a big data dump. For all their mad programming skills, their database design sounds like junk. some good data modellers might do wonders for them.
