It's not a huge deal, but I have to say that if you're used to one format, it's really annoying to suddenly have the other, especially when dealing with dates like 10/2 (February 10th for me, presumably October 2nd for others?). Using the month as opposed to a number avoids this issue.
I keep confusing myself about the dates if they're shown the "American way" (2/11 for February 11). Even if I know, I often have to look twice and see if I see a date that contains a number between 13 and 31 to be sure about the date.
I would prefer to see the dates containing the month spelled out (Feb(ruary) 11), rather than in numbers, regardless of the format (11/2 or 11/2). OR have an option in our profile to choose how we want the dates to be shown.
