(Before I commence this post, I will readily concede that I am looking at this through the worldview of a non-disabled person, and so my opinions are informed accordingly).
When I first heard about DC's decision to “reboot” a lot of their main characters, I was tickled pink. My interest in the comic universe is a fickle thing, usually inspired by movies with hot Wolverines or Batmen interesting superhero storylines, but I always get frustrated by the fact that I have to read back like 50 years to get the whole back-story—and then let's not forget the a/u story arcs! So to have Batman and Batgirl (among many others) reboot to Issue #1 is a great opportunity for me to get my geek on with relatively little effort.
I received the news about Barbara Gordon/Batgirl/Oracle “rising again” with more ambivalence. I am delighted to see her be more mobile and take on the traditional superhero mantle (so long as she does not give up her mad brain skillz); I think that often, in our society, women are relegated (and often relegate themselves) to a more passive, hands-off, intellectual/intelligent/smartypants role. One needs look no further than the American Community Survey, which is showing that 34% of women ages 25 to 34 hold a bachelor's degree or higher, as opposed to 27% of males in the same age range. So it has sometimes felt to me as though Oracle was typecast as the smart, behind-the-scenes, not-allowed-in-frontline combat character who was, through her disability, unintentionally reinforcing this new gender role for women.
Don't get me wrong. I am a librarian. I love to put people (men, usually) through the mincing machine of my brain. I recognize the need for women to show off their smarts as much as possible. And I recognize and honor what Batgirl came to represent to many people, myself included, through both her brains and her refusal to be restricted in what she could do due to her injury.
But the times, they are a changin'.

Batgirl: She's not just your symbol, your role model, be you a woman or a man or a person negotiating a disability. She's here to be a symbol and a role model for everyone, should they want her. She was disabled and confined to a wheelchair. And now she's not. Just as one is more than their hot body or beautiful face, so too can they be more than their disability or their wheelchair. It's their mind, their strength of spirit,their talents, their character which is the true role model. Everything else—their wheelchairs, their capes, their fancy gadgets—all these are just trappings. Her wheelchair is not an essential part of her personality; her brains are.
While I understand, at least on an intellectual, if not emotional, level what Oracle represents as a disabled person, to disabled people, she is more than her wheelchair. The story arcs of her as a disabled woman don't cease to exist; they simply re-boot. Oracle, Batgirl, whatever you want to call her, will still be there, just not in her wheelchair. Be angry if she loses her stellar brains, her ideals, her integrity, folks.
I understand how essential it is for us to be given examples of diversity though pop culture. We “other” people all the time, and shy away from them. Disabled people. Minorities. Women. Weird people in Amish garb. Little people. San Francisco liberals. Undocumented immigrants. You name it, someone is gonna be hatin'. And I suppose I could be accused now of “othering” people in wheelchairs because I am supportive of a Barbara Gordon that I can personally identify with—that is, a Barbara Gordon who is not confined to a wheelchair. It's neither my desire nor my intention to minimize the substantial obstacles any “other” in our society faces; I acknowledge them and honor every person who faces their obstacles head-on. But what it boils down to is this:
It's time to share her with other people; Oracle or Barbara Gordon or Batgirl doesn't need her wheelchair or her disability any more. She had it, it served as a beautiful, inspiring, and substantial storyline for years, but it's time for other things. We all need Barbara Gordon—as well as many other role models—but all Barbara Gordon needs is a large market of people who need her—and that means everyone, male and female, disabled and otherwise.
Was it DC's intention to turn Barbara Gordon into an iconic role model for the disabled segment of the population? Were they simply trying to get rid of her, make people hate the Joker even more, and then suddenly realized that they had stumbled onto something big, both as a marketing ploy and a vehicle for change and acceptance? Who knows? What I do know is that DC is being equal opportunity: everyone gets a reboot. If Barbara Gordon didn't get some sort of reboot, that would look very odd indeed. Her wheelchair never really stopped her before—and so it won't stop her from being rebooted, either.
