Jake,
Your silents is came accross as no interest. So I stopped responding.
I hold onto the queue idea because it will slow people down on loading up junk because they know that someone/thing is going to say yea of nay.
Also you could have a moderator rating system since they would be more critical and hopefully most truthful. Just like Cnet's download people give their reviews more wieght than users.
Just this morning I was searching for Carrara models every item was subpar. IMHO
The flat pay, can also be teired so that works the moderators think are high quality can get high per view rates. This would also encorage developers to actually but some serious effort into their work.
Also I think you need to have a PRo's area, so that people know right away were the best work is hiding.
Here' another thought that most people wont like. Memebership with a small fee where the membership fee's can be pooled and devided up between the content providers.
Just thoughts
