Hello from a relatively new brony! I found out about this MLP somewhere around a few months ago, and have been watching on YouTube, and currently I've watched pretty much all episodes at the point of posting (up to s2ep12).
Some personal things:
My favorite pony (well, "pony" can be discussed) is Discord. This is because I'm a Trekkie at heart, and I absolutely love Q. Next to Discord, it's everypony!
About "coming out of the stable", I have no problem with letting the public know and haven't been "hiding myself" to that spectrum, but for friends and relatives, it's rather difficult for me to "stop hiding".
