Fandom involvement
Miller was highly active in the Friendship is Magic fandom during his tenure as showrunner, hosting numerous Q&As and appearing in a number interviews with fans. Notably, he appeared as a guest on Equestria Daily's recurring column, From the Horses Mouth as a guest of honor and appeared at several fan conventions.

In 2019, Miller was sent death threats after Friendship is Magic was leaked in Netherlands, causing a support campaign known as #ThankYouBigJim to thank him for his then nearly 10-year tenure as a show staffer.

When Friendship is Magic officially ended, Miller made a several tweet-long eulogy of the series, praising the staff and fans of the series.
