IDK... but it makes sense to keep his gaming business separate from Newgrounds. Tom was always a game developer first, but he made Newgrounds for other game developers to have fun, try out new things, help new artists and programmers get better, hang out. I think the world changed, and Newgrounds stayed the same, which isn't a totally bad thing...

Tom makes so much more money from his games, and NG has been making less money since 2007, so he cut his staff :p

Thats why he is paying other staff (friends) to help newgrounds live longer?
