I still regularly follow music, fan-art and to a lesser extent any pony related material people likes on Youtube.
But I don't sit around thinking of ponies 24/7 and I certainly wouldn't think about talking about them outside the internet so I don't consider myself a brony for those reasons, and pretty sure the media has made "brony" a dirty word anyway so I wouldn't want to be.
I wish I had gotten into the music part of the fandom much sooner than I actually did. Now there's so much of it and impossible to keep track on everything (not that I was possible to do so earlier but it's not getting easier haha).
As for other activity in the Fandom, I've sort of stopped going to Equestria Daily. I think I need something else just for variation and not suck the hobby completly dry.
But what? hmm...
John de Lancie and some other people producing a professional documentary about Bronycon and the MLP phenomenon in general. They need at least $60k in donations (though it appears that the minimum amount will be well exceeded).
I would definitely recommend donating whatever you can to support this project. There are even some rather compelling prizes you can get for donating a certain amount.
I was about to ask who in their right mind would actually pledge 10k just to get those prizes, but then I realized that people have spent thousands on plushies/fursuits. That value suddenly seems a lot more feasible.
I'll definitely be donating some cash myself though. I'd love to see it take off.
I seriously can't favor any song from the show over another. They are all truly magnificent in their own way, more or less (Well, some ARE better than others though.)
I mean...do I even need to get started? Nah.
Every now and then I come back to listen to Season 1 songs, only to jump back to "present" and the season 2 ones. Heck, I can't decide, I like them all.
I might try on making a remix of one of the songs myself eventually. Been thinking about Art of the Dress, but would it be considered "too late" for that by now?
Not much progress in terms of gameplay, but heaps of it in terms of the co-op part apparently (although 3 player co-op doesn't seem to be happening by the looks of it).
Not sure if he is actually working on the CMC part of it at all any more or if he's just working on the general co-op sprite and stopped the CMC hack.
