It is weird that 'WHO IS BATGIRL?' has become the bigger mystery over 'WHO IS BATMAN?', but it's still entertaining enough over at the 'Rama with people whingeing that it has to be Babs because she's the only one with the right to the cowl after Cass.
And as much as I love Cass, she really got a raw deal over the past couple of years, so perhaps it's time to either do something solid with her, or leave her alone for a while rather than annoy people with poor portrayals. As it is, given her sister/aunt/whatever has returned to prominence, why not give Bette Kane a spotlight in the mask for a while? Frankly, she's the only one I can think of who'd explain that particular smile on the first cover.
Plus - The Joker - still under 'at large'? Given his lack of appearances as of late, why not just leave him alone entirely and save him for the final Dick as Batman story that we'll inevitably get?
