This is a good opportunity to share my REAL answers to these questions after that embarrassing sleep-deprived rant I did for that random dude at MAG.
1. Why do you think so many people submit and share their remixes to OCR?
I think the people who submit, get posted, and stick with it continue because they understand the advantages of having music released through OCR, such as being a part of the larger vgm community and having their music be heard. OCR has become a really good place for quality music, and being posted is a testament to someone's abilities as a musician, especially if they struggled hard to get there.
2. Why do YOU do it?
NO REASON AT ALL! BWAHAHA!! Kidding.. haha... If it weren't for all of the remixes I made over the last couple years, I probably would not have improved as much as I did as a musician. I make good stuff now, and I have OCR and specifically people like OA's input to thank for that. I still remix after having so much lined up to release because it is a hobby that I have grown to love, even though it takes SO LONG for the music to get released here. TOO LONG! I'm growing as a musician to places I am discovering and that are different from where I would have thought. Also I keep doing it because I feel like it validates my inclusion in the community, otherwise I would probably disappear again.. for years... like I did between 2001 and 2009...
