nosql - Using a Relational Database for Schemaless Data - Best Practices

Question

After reading a shocking article written by Bret Taylor (co-creator of FriendFeed; current CTO of Facebook), How FriendFeed uses MySQL to store schema-less data, I began to wonder if there are best practices for using a RDBMS such as Oracle, MySQL, or PostgreSQL for storing and querying schemaless data?

Few people like to admit they're using a relational database when NoSQL is the new hotness, which makes it difficult to find good articles on the topic. How do I implement a schemaless (or "document-oriented") database as a layer on top of a relational database?
