She has written for various series on MTV, including The Tom Green Show and the annual Video Music Awards and for other Viacom-owned networks, includingVH1, Comedy Central, and Nickelodeon. She was also a cast member on the (unused, early working version of) pilot episode of the reality TV series The Real World. In April 2011 Grandstaff conducted an interview with the website "Can I Get a Man With That" to promote the DVD release of the complete series of Daria.
On her view of the character eight years since the finale, Grandstaff said, "She is, was, and always will be The Misery Chick who loathes attention more than she loathes herself. Eight years later, there are new things that would totally annoy her—primarily words like totally and bestie. ...I don't see her as a sad character. I see her as tolerant of her unavoidable reality—eager to put the whole miserable experience behind her, so she could get out into the world and surround herself with people she actually admired and respected, or not."
