Sure.
1) Yes. I've never had a problem finding things, even when I was starting out here, oh so long ago.
2) Just a general opinion. I don't really use the WiP for feedback, just for releases.
3) I don't really review. I don't have a lot of time too, plus I'm a Judge so when I do find time I prioritize the queue.
4) I think people just need to try to use this place more; I think the open, normal forum aspect of it hurts. People would give more feedback if they had a more structured system to follow, and that's something we're looking into staff-side.
5) A few things:
I don't like it when people say "I don't comment on the WiP board because I don't feel like I can give good feedback." There's only one way to learn how to do that, and it's to just sit down and do it. It's alright if you can't articulate yourself well in the beginning; you'll learn how to do that with practice.
I also don't like it when people use the WiP board to post their work for feedback, but at the same time criticize OCR, its standards, and its staff (i.e. the Judges Panel). That's very rude. OCR provides this forum as a courtesy to you so that you can get your music out there for the world to hear without having to wait. You can dislike the site, the staff, the standards, or even certain individuals, but please, if you're going use this forum, keep it to yourself. In other words: if you're invited to someone's house for dinner, don't go there and eat the food, but insult the cook and host. Show some courtesy and appreciation.
People should respect the wishes of the original poster and make sure they read what the original post says before listening to the song and posting away. Few examples: if I say "This is a release, I'm not working on this anymore, please enjoy," don't reply with a list of things I should change; I said it was done. Another: If I say, "This is only halfway through the song; that's not how it's going to end; it's going to be a lot longer. I'm just looking for feedback on style, soundscape, and production," don't tell me, "The ending just cuts off! You should write a real ending!" Please pay attention to what the artist wants.
