Is a public message at blockchain.info embedded in the actual block chain? When sending a transaction using a wallet at blockchain.info you can add a public message. This message shows up when viewing the transaction at blockchain.info. 

Is this message embedded in the actual block chain or is it just a record in the database of the server of blockchain.info?
It did for a few days, before the blockchain.info operator concluded blockchain bloat was not good for Bitcoin.  Now those are only stored on Blockchain.info hosts.
