Tom has been talking about it for ages, but it has finally happened. Newgrounds is getting redesigned and getting a ton of new features (see below).

Site-Wide

No more pop-ups. Period.

100% valid HTML + CSS… even in the Forums.

User Pages

Blog-style news section moderated by no one but you.

Your flash, audio, and favorites all showcased under a customized header.

Stats and info redesigned to reach your audience more easily.

Audio Portal Changes

Featured audio playable right on the Audio front page.

Audio submissions now include album art.

Audio visualizer on every song page.

Flash Portal Changes

Enjoy games & movies like never before.

Expanded submission info in the main listing.

Streamlined submission process.

In-page commenting and voting.

Tons of Other Stuff

New wallpapers, icons, & Flash aids.

Access to all your tools from one convenient location.

A search that was hand-tailored to NG content.

New emoticons, secret items, level icons, auras… and the return of the Bytesize player.

Sounds like they are trying to let the users do more than just submit and vote on flashes (much like deviantArt)
