It's pretty jarring, as y'all know, so it doesn't do to have as the default sound, but it it's great for important contacts that don't message much.
Honestly it's a bewildering choice for the default "message received" sound of an IM client. It's so very alarming. I can only guess that the makers were expecting you to be a room away from your tower PC (with its deluxe 18" CRT display and mouse cables that required a screwdriver) to make sure you never missed a message.
These days, when you're never more than a layer of fabric away from your IM, it's a bit much. But man, effective.
Onwards and upwards! Bigger weapons than before!

The arms race: crazy, simply way out of control.
