Folks,
We are seeing an increase in the sarcasm and snark in this thread. That makes it a perfect time to remind you that sarcasm and snark generally don't work well as teaching tools. If your goal is to get someone else to see that you have a valid point, sarcasm is *not* a place you want to do, because it will more usually do the exact opposite. Sarcasm and snark tend to polarize arguments and sides, and make nasty argument more likely.
So, please consider leaving the snide stuff at the door. Thanks, all!
