I just use IM for quick arranging or linking stuff around. Can't understand how people can chitchat on IM with each other for hours. You never now if that last message was supposed to be funny or serious or maybe even ironic? Then you don't know if your conversation partner thought your last message was serious, while you meant it to be funny...and it goes on an on and on... just can't do it.<p>Don't have any problems with normal conversations and phone calls though.
