Eric, Jonathan Gray said it very clear at his talk at BerlinBuzz: Facebook is now using HBase instead of Cassandra. http://berlinbuzzwords.de/content/realtime-big-data-facebook... You can find a lot of info about the FB process to choose HBase in favor of Cassandra. This one for example: http://facility9.com/2010/11/18/facebook-messaging-hbase-com...

That's exactly what I'm talking about: that facility9 blog post explaining why they chose HBase had many factual errors about Cassandra when it was posted, and had to be revised after several respected people in the space contacted the author.
