MacDonald is a former editor for DC Comics' Vertigo imprint and Disney Adventures, and also edited the graphic novel The Hills Have Eyes: The Beginning from Fox Atomic Comics that served as a prequel to the 2006 film. She created her long-running blog "The Beat: The News Blog of Comics Culture" at Comicon.com in June 2004, before moving it to an independent site in 2010. She also served as an editor and writer at Publishers Weekly.
In January 2016, MacDonald announced she was laid off from her position at Publisher's Weekly, and was moving her blog to the webcomics site Hiveworks. She wrote, "The era of the 'bedroom blogger' is long gone, replaced by corporate entities trying to outdo each other with clickbait headlines and subsisting on popup ads that get more bewildering every day.".
