How would I explain the following phrase/expression to an ESL learner?
"Keep those cards and letters rolling in"
I actually don't know where this comes from, or what it exactly means.
Any help is appreciated!

It comes from radio shows where they read postcards and letters sent in to the show from listeners. Without new listener material there would be either more work for the producer to do in order to fill the radio slot, or they might not have a show at all to put on if the listener material was questions regarding a general topic such as, say, home repair or relationship advice.
