on the topic of 'Batman Incorperated'

There a thread on the Spacebattle forum (well, a series of threads really) called 'Bruce has a Problem' that has become a round robin story. Basicly, Harley Quinn, upon hearing the announcement, realized that Batman is 'too much of a control freak to let someone else control his purse-strings' and realized Bruce is the Bat.

Being Harley, she then leapt to the conclusion that Batman has been 'courting her' all those years with the battles and Wayne funded attempts to reform/cure her. So she decides to dump Joker and join her new love, Batman.

the first chunk of the RR deals with the Batclan (and some of the bat-villains) trying to wrap their heads around this development.
