For me it feels like laddering is only for winning, nothing else matters (of course). Not for having fun. And cos i don't have time to play anymore, I don't play ladder.
So shame SC2 doesn't have the same social atmosphere SCBW did (no chat channels), it would be so much more fun (don't get it wrong, i'm not saying SC2 is in any ways worse game than BW, i don't wan't to compare).
So: No ladder -> No rage
