When news of the reboot hit, reaction was mixed to say the least. And when it was announced that Barbara Gordon was taking the mantle of Batgirl, it didn't make things better, especially with fans of Babs as Oracle, the mantle she had held for twenty years as a handicapped character. This really struck a chord with Jill Pantozzi of Newsarama, who like many disabled comic readers, viewed Oracle as one of the best postive examples of those with disabilites in fiction. Jill wrote a strongly worded response to the announcement to show how hurt she felt by the news. Gail read the article and was so touched, she contacted Jill and gave her the first interview on Batgirl. Let it never be said that Gail doesn't care about her fans in the slightest.
