What is it that drew you in?
I first noticed the "brony" phenomenon online in 2011. I thought "Dudes, watching My Little Pony? What's up with this?!?". Eventually I noticed there were full episodes on YouTube. On March 23, 2012 at about 10PM I watched Season one Episode one and thought "This isn't bad". I watched the second episode and thought "This is pretty good actually". By the third episode I was like "What the heck have I gotten myself into!?!". In less than an hour I was hopelessly hooked. I quickly watched all the rest of the episodes, joined the meetup group, made a bunch of nerdy friends, was in an a Capella singing group for a while and have been to BronyCon three times. It's been an amazing experience.
Unlike most cartoons MLP-FIM is well written (closer to adult sitcom level than kid's show)with complex, relatable characters. Many bronies are introverts and the show is like Socializing 101. The fandom is amazing; incredibly friendly and accepting along with being wildly creative. Try keeping up with all the fan made art, music and videos.
