The Brony Phenomenon? A fad? Yeah I'm gonna go out on a limb and say... no. I believe that Bronies are here to stay. Name one fad that got conventions, brought people together, inspired so much charity, created entire communities on forums and in online games, created countless volumes of music, art, and videos. Name one fad that led some people to happier lives and, in some cases, sparked their desire to write, sing, draw, etc. Honestly I'd say it's far too soon to predict anything about the future. To my knowledge, nothing like the Brony Phenomenon has ever happened before. So who knows where things will go?
