Instant Messaging: any good?

This thread on IM just came up and I commented thus.

I had originally written in the list of delicious experiences, "Been privy to the most depraved halogen-lit whipped-cream-enhanced parking-lot sleaze of my life. So far." But decided against including it in the context of some guy talking about his daughter on IM. Heh. Who knows whom you might meet online... :-)
