Ok, here are a few ideas. I think a lot of people may agree with them.
1) Why not simply avoid the controversy and have TWO numbers, one a true "batting average" and the other the "top 3" average? That way we can reward both the most consistent submitters AND the ones who made just a few very good flashes. There can also be 2 different artist top-50 lists, one based on the "top 3" and the other based on the actual "batting average". More statistics on Newgrounds never hurt anyone - in fact, going through those statistics is the main way that I find interesting stuff on Newgrounds (aside from the front page).
2) With all of this revamping that's going on, the audio portal needs to be fixed as well. Stop goddamn ignoring it. First of all, would it be possible for me to actually SEE THE REVIEWS THAT I'VE WRITTEN for audio submissions on my user page (they should be on a separate page from the flash reviews), or at the VERY least have a FAVOURITES list just for audio submissions?
See, the problem is this: my way to "bookmark" interesting flash submissions is to either write a review for them or to put them in my favourites. Neither of these options are available to me in the audio portal. Seriously, what the hell? Am I supposed to just memorize the name of every single thing that I like, or write it all down on some piece of paper? We're not living in the goddamn Middle Ages, are we?
Also, there should be a certain time period (maybe a week, like in the flash portal) before a piece of music is added to the top-rated-of-all-time list. I see way too may "5.00/5.00"-rated submissions in the top 50 that only have ONE vote, while the actual GOOD MUSIC begins some distance below. This badly needs to be fixed.
Unlike a previous user, I see no problem at all with the 1-5 rating system on the audio portal. How am I supposed to know if something is good, after all? Definitely keep it. But please, fix those problems that I mentioned above.
Thank you for reading (well, I HOPE someone is reading :P).
