Our “Stick With It” conversation series on the Top of Mind podcast continues with historian Greg Jackson’s story of committing to get the regional accents right on his podcast “History That Doesn’t Suck.” A few years ago, his audience had grown so large that he was immune to most listener criticism. But a message from “Lucy in Tennessee” about the Southern accent Jackson affected in his storyteller cut through the noise. Jackson chose to stick with the discomfort of that criticism and step up his accent game. His podcast is better for it.
