I approve of this, not only that but is going to be like a month or so i was talking with Me. VicariousE about what if NG had an app that allowed to stream speed paint or tutorial videos, but not only that it also allowed for collaborations, and file conversion in real time, then the finished painting could be uploaded to the art portal, and the video will remain in the its own section under speed paint, or tutorials, Jazza recently uploaded a video on YouTube about increasing his programs, and was talking about making a section when he would hang out with his fans, wouldn't it be great if that was done in Newgrounds? that way the making, and hosting is all in the same place, he could always upload it later on to YT if he wished so, but it all would be taking place here.
http://sabtastic.newgrounds.com/news/post/852800 in here it was that idea started, originally was going to be a game like the drawing grounds, but a featured application would be nicer, and increase the traffic to the page, and in that case the speed paint and tutorial videos, while still being movies could have its own place in the art portal, that way avoiding conflict the more traditional videos, on the other hand i don't know how the featured and top 5 would work under that scenario.
But regardless of all that i absolutely thing that NG should adopt this media.
