I think when I first came here, it took me time to come to appreciate the tremendous amount of help you guys give (call it early ignorance), but looking back, I think I was most inspired by @zircon, @WillRock, @Chimpazilla, @Gario, @djpretzel, and of course @Liontamer, who could forget him?
zircon is kind of an obvious one --- I learned most of what I know in music from studying his, from watching his streams / remix walkthroughs, etc. It has also been a pleasure and a joy to do sound design and to test Super Audio Cart (SAC) and SAC PC.
I've generally found Willrock to be someone who really made an identity for himself; he isn't afraid to express himself, and he makes music that is clearly identifiable as his own.
Chimpazilla has been a good influence on me from nearly the start, and inspired me to realize that collaboration opens you up to new ideas and really supports you in areas you still need to work on.
Gario is like a super-mod, who is also very empathetic, and eloquent. He inspires me to express my feedback in both clear-cut and respectful ways, and in essence it's great for my character.
djpretzel has a great sense of humor and writes excellent ReMix writeups, and does plenty of behind-the-scenes administration, advertisement, and legal stuff for the website, youtube, twitter, etc. while not necessarily getting the thanks he deserves. Without djp, we wouldn't even be here now, talking about... each other. Woah.
Liontamer is honest, direct, and pleasantly sarcastic. If he had to, he could probably carry the legacy of OCR on his shoulders, and he really embodies the spirit of OCR, IMO. He's also damn funny.

If I forget anyone, it's not a knock on you, by the way.
