The yyyy-mm-dd hh:mm:ss format is ISO standard. It has some obvious benefits: 
alpha-sortable, not likely to cause confusion to people as could happen by 
mixing European notation dd-mm-yyyy and US notation mm-dd-yyyy... if you only 
have the choice of storing the date as text, yyyy-mm-dd is the way to go.

Of course what you display to your users does not have to be the same as what 
you store in the database. With a few lines of Perl code you can transform 
yyyy-mm-dd into any notation you like. Something like the following would do
the trick (warning:untested code ahead!)

[perl]
	my $date="2002-03-04";
	my @months=("jan","feb","mar", "apr", "may", "jun",
			"jul","aug","sep","oct","nov","dec");
	my @datear=split("-",$date);
	my $year=@datear[0];
	my $month=@datear[1];
	my $day=@datear[2];
	return @months[$month-1]." ".$day." ".$year;
[/perl]
