What is the best way to keep windshield wipers in good (low ice build-up and ready to be used but not a partial job because of above mentioned ice build-up) working condition during a snow/freezing rain storm? I have seen some people with them stuck out in the air. Other people have tried a towel over them.

Sticking them straight out works good in snow and ice rain, but is best when used with a towel, socks on the wipers or other waterproof cover. Ice getting into their joints stops them from working and can be a problem even if they are sticking straight out. Spraying something on the windshield works even better with this.
White vinegar is suppose to limit the amount of ice that builds up, but I fail to see how this would be useful in vigorous rain. There are products built for this and if used liberally then they do work.
This SE question gives some good feedback: https://mechanics.stackexchange.com/questions/5521/should-i-pull-my-wipers-away-from-the-windshield-when-parked-during-a-winter-sto#
Putting a tarp over the car helps and there are pegs created to stop them from sticking to sticking to the window shield.
