I wonder if being part of Facebook (from which Cassandra originated) has anything to do with the choice for Cassandra over other databases.

Apparently Facebook is not using Cassandra much. For their messaging project they ended up with HBase instead of Cassandra [1]. I don't know if the system replaced the earlier Cassandra system, or complemented it.
