think of it this way...
AIM is the newb, he think's he's so great and smart, but always asks "gimme teh codez!" annoys the hell out of you, and rarely does anything.
YIM is the programmer girl that everyone likes and wants to "get to know", or wants to her to "show teh boobiez", but she's really just a sad fat man who programs in pascal.
ICQ is the cool chinese guy who you can't communicate at all with, can't design to save his life, but he knows how to program a functional app.
MSN is the oldbie who isn't a complete fatass taking up all your room, he knows how to program an app that's useful, that does backflips around the competion, knows how to make it functional and knows how to make it look darn sexy to boot.
