Oh yeah, I forgot, depending on how high your ceiling is, the further
you dangle the fan down the better, until you scalp yourself. Making
the air turn a tight corner between the fan and the ceiling puts a
crimp in the circulation.

A ceiling fan won't have any wobble, nor problems with air circulation,
if it's mounted on the ceiling. In colder climates, during the heating
season, circulating the warm air at the ceiling down to where people
actually live is preferable - the higher the fan, the better.
