I think the WIP forums would need a MAJOR overhaul before it could be any kind of viable service similar to VGMix. The forum showcases MAYBE 5 mixes on the front page, which I'm sure would be changed, but how long would you display songs on the front page? What would determine how they actually STAY on the front page? (right now it's per-reply, and that hardly seems like a fair system). Even so, having a link to the forums on the main page helps a lot, is it REALLY better than having it on (an ideal) VGMix system? Would it actually get a good amount of exposure? Who knows.
This is completely ignoring the fact that right now trying to find something in the WIP/Completed forum is an absolute nightmare. Back during the original forum reform, I offered up a solution of a sort of "standard" for posting in the WIP forum that would make it a lot easier to at least READ, and I remember Darkesword agreeing, I don't remember anyone else even responding, and nothing has happened since.
BUT I think what's MOST important here...is freedom. I think the real reason VGMix exists is because artists want to have more freedom with their music. Freedom to do whatever they want with their music. Even if OCR had a similar system integrated, I feel like people would post on VGMix still...because they can. No offense to DJP, but a lot of times things at OCR come off as "Well this is my website, and I'm going to run it the way that I want it, no matter what anyone else says" which may or may not be the case, and it's totally JUSTIFIABLE because it IS his website, but that in itself just makes people want to have more control of their songs. That being said, it seems like it'd be LESS of a "community divided" issue, so much as it is a FREEDOM OF CHOICE.
Isn't that the real reason VGMix was made in the first place? Because people wanting more control over their music (and a bunch of other stuff, I know)?
