As a follow up to our experiment of asking people to check in with The Takeaway as they go about their daily lives, we turn to the man who suggested the project to begin with, our producer Jim Colgan. He joins us to explain why listeners, like our other guest, Richard Lavely, would want to call in and why others just didn't get it.

For more on this experiment, listen to our earlier segment, then to our even earlier segment, read Jim Colgan's Producer's Note on the fun of playing with the radio, and check out Buzzfeed.com Senior Editor Scott Lamb's post on the absurd of satisfaction of playing Foursquare.

Today the Takeaway is asking, "What are you doing right now and what's on your mind?" When we asked a similar question last week we got hundreds of responses. But some people said they didn’t care. One of those listeners, Christine from Brooklyn, talks to another listener, Richard from Hazel Park, MI, who tells us why he took part and why he wants to hear other listeners "check in".
