1) Of course; well aware of all these things.
2) The main thing I'd like from the WiP board is specific critique when requested. In my last wip thread, I asked for advice on the arrangment because I knew the mix sounded bad with just the midi sound. Only after PMing zircon did I actually get a good response about the arrangement and what I should do to improve it.
3) I may get a finger wagged at me for this, but I'm still one of those people who only listens to remixes from games they've played. Now, don't get me wrong; I'm a judge at OLR and I have to listen to everything that comes through, but I would rather listen to remixes that I know exactly where the source comes from in it's context. I'm sure I would not have the same attachment to some of the songs/remixes I have if it weren't for this fact. It's more of an emotional conection with something you recognize, you know? I think it also helps you decide what the remixer is trying to do with their mix and could help give you (the critiquer) some ideas for them.
4) Overall, I think things are good for the way they are. Granted, there could always be more critique, but people are busy and don't always have the time.
5) The fact that the judges are rarely here unless they're teasing us with a new WiP
