I hope these are already in the pipeline for the redesign, but I figured I'd get them down in text anyway. It would be interesting to see what you guys think, and maybe we'll get official word on what is and is not a realistic feature for the future.

I love newgrounds, and I don't want it to turn into Facebook or anything, but my number one feature request would be some sort offollowing system.
If you find an artist you like, you can follow, or subscribe to them. Whenever they post new content, a message about the content lands in a inbox / ticker. Additionally, artists would be able to create sub-categories for their works so that serial works could be subscribed to specifically. For example, you could subscribe to the Awesome series from Egoraptor, and only get updates when that series is updated.

I feel like something that holds some artists back from having a real following is the lack of simplicity in tracking them. Yes you can add them to your favorites list, but that requires you to dig through your account page, and check all of your favorite artists each day to see if something new has been posted.

It would be cool if this same ticker / inbox would notify the user when an artist responds to a review they have created. Again, I know you can find these things, but the process is far from streamlined.

The ticker could also indicate new reviews posted on your own works. It might be best just to show a number, as popular works can receive many reviews. I find that I get a random review on one of my old works every now and then, but I don't discover it until I happen to be browsing through ALL of my work.

Why can we post as many youtube videos in a news post as we wish, but only one highly limited image? I'd love to see a revision to that.

I know there is no priority what so ever to upgrade the audio portal at this time, and I also understand that everyone is well aware of the zero-bombing that happens there, but should it ever get looked at:
*Songs should have to be allowed to play for a few seconds before a vote is cast.
*Users who submit to a given category are not allowed to vote on other works in that category for some time.
*Users have some sort of rating based on their audio portal voting habits. If they vote 5's all the time, they're one rank, and if they zero everything, they are another rank. No rank is 'better' than the other, but this would illustrate that user's voting habits. Zero-bombers could not hide :P
*Users are not allowed to vote on their own works! I'm shocked that we still can. Everyone's submissions fly to the top of the list when they 5 themselves for the first time.
*Why can we vote twice on the same work? Even at 24 hours apart, I've had disgruntled people who swing by every day for a week to zero bomb something. This goes for flash submissions as well.

In closing, let me clarify that I'm not dissatisfied with Newgrounds as it is now. My suggestions for improvement should not be taken as an insult to the hard work that has already gone into the site's design.
