### Sending volatile messages.

Sometimes certain messages can be dropped. Let's say you have an app that
shows realtime tweets for the keyword `bieber`. 

If a certain client is not ready to receive messages (because of network slowness
or other issues, or because he's connected through long polling and is in the
middle of a request-response cycle), if he doesn't receive ALL the tweets related
to bieber your application won't suffer.

In that case, you might want to send those messages as volatile messages.
