Wii Warm Up: The glow

We're all familiar with the pulsating blue glow that tells us we've got a message. Some of us find it futuristic, others creepy (it's like it's breathing or something.) How do you react to the Wii's alerts? Do you check your messages immediately, thinking that this will be the time it's important, or do you prefer to leave the pretty blue light on as long as possible?

Also, do you ever send messages to your friends' Wiis just to turn their blinky light on? We have, on occasion, for a friend who does the same for us! It's blinky, you see. The light blinks.
