Let me say first, I love the redesign. The graphics are awesome, and the site looks cutting edge. I actually consult on website usability.
However, there is one thing you need to change about the re-design, something you MUST change or the number of users on the site will slowly be greatly damaged:
I, like every other Newgrounds user, appreciated the few sentences about the different games and movies on the home page of the old design. Why? Not for their humor, etc. but because games aren't adequately summarized in just a picture. The few sentences such as "Unique physics based tower defense game" in the old design was enough to tell users that if they like tower defense games, they should give it a try. In the new design, I see a pretty picture, but have no idea what type of game it is most of the time. You may think this makes users try more games, but in reality it makes impatient (all) users get pissed off and leave because they aren't going to wait to load and wait through the ads to realize its a third game that isn't the type they like to play.
