Sort of. She gets a passing mention as one of the "Forgotten Characters," along with Donna Troy and Wally West.
Now, you may be too young to remember, but there was a time when she was an active character and dividing fans. It was around the time of "One Year Later," when I was blogging about her and a few others here and there were also adding their pro and con views on Cass. I remember one particularly trenchant and well-written anti-Cass piece entitled "Of Course She Is" or something along those lines. It was one I obviously disagreed with-- and I've forgotten the specifics now but you can probably Google it and bring them to my attention for what it's worth so many years later-- but those were days when mighty voices made thunderous noise from their blog mountaintops and even those of us in opposition did listen to the din and tremble before launching our own lightning bolts.
Comicbook.com gives good ol' Stephanie Brown her own entry but you know what? I don't see her so much as divisive as uniting. I made a little joke about her a while back, a Steph fan took it to her own blog and she and her friends decapitated it and kicked the head around like a soccer ball. Roasted the body and displayed the charcoaled bones on their sacred purple bat-shaped altar. That's how I learned that my, my, you do not want to mess with Steph fans. The Comicbook.com list even talks about Steph as being symbolic for those not too pleased with the whole of DC's New 52. Rally 'round the Steph, people!
