An “information refrigerator” requires you to actively pull information. It’s like having to open a refrigerator door, reach in, and retrieve the information. Example: Word document on shared file storage.An “information radiator” pushes information to you. Information radiates from it. You can’t ignore the information unless you actively try to avoid it. Example: Card wall.
NOTE: I will be rather harsh for instruction purposes
