my crack at some linkage

Well I've been meaning to go on a crusade against sarcasm, but Terry posted a good link on it today here from the NYT.
Sounds like the trick to it is to figure out what other's are thinking. The article deals with it from the perspective of the listener knowing what the speaker is thinking, but I think that when sarcasm is really effective, the speaker also knows what the listener is thinking. Regardless, if it cannot be abolished it needs to be cut back big time. It is like many good things, best in small doses.

He seems to make a better case for McCain, though he has appeared to be pulling for BO more from past posts.

Sorry, flip-flop lovers. You may be hurting yourself.

And, another opportunity cost related to consumer debt, your health.
