I have always loved MLP (have several reassuringly large bins of G1s and no few G3s)
At SakuraCon this year in Seattle (March or whenever that was) I saw a bunch of people dressed up as ponies and a lot of pony customs costumes art and STUFF. I was pretty impressed and learned about the FIM series. Ran home immediately to check it out on Youtube and watched them ALL. I was really shocked how fantastic the series was- particularly the opening and the conclusion. I can't wait for the next installment.
I love the brony FIM fan base too. I am not a brony- but it is also not considered entirely appropriate for a 30something attorney to love MLP (or childish things in general) so I can relate somewhat.
Anyway, hi and hello- it is nice to be here
