I'm not saying it's significant but someone who's standard practice is to fill up from half is either fueling too often (Your extra idle and pulling in and out of gas stations) or has their eyes on the wrong prize. Unless there is something to this water thing [Citation needed.]
Another good reason to keep your tank topped up is because while chances are you will be able to fill up tomorrow, that might not always be the case.
Do you remember the great power outage of 2003? Some areas lost power for 2 days or more, and with no power most stations weren't operating, so if you were on a 1/4 tank or less you wouldn't be going far.
Saying that, I rarely ever get around to filling up at 1/2 a tank... I keep procrastinating until I have to fill up as I've got other things to do.
