Like Essence this weekend, last weekend’s BET Experience, held in Los Angeles, had Beyonce as a headliner. It also had panels discussing topics important to the community and spanned a three-day weekend — a format Essence until recently had used for years. But Michelle Ebanks, president of Essence Communications Inc., said the similarities end there.
