If Lil Wayne liked Newgrounds, would that mean a huge amount of people would flock to NG and start using it and become members of the NG BBS community?
For example, a while back, Lil Wayne did a pose where he put both his hands over his mouth and it was released all over the web, and many people, especially fans of Wayne, put up default profile pics on Facebook of them putting their hands over their mouth, in the style similar to the way Lil Wayne did so.
A lot of people will copy anything Lil Wayne does that is perceived to be awesome, so imagine if this happened but with NG... like him wearing an NG T-shirt or something.
