I dunno bro,
I enjoy NSG because its a place to discuss things with likeminded people, I feel like that if I want to watch funny videos/look at amusing web pages reddit is the place for that. NSG for me isn't about random content from outside, it's about the community and stuff like that.
Think about it, all of the memorable NS stuff (Chad's, Solid 7 stuff like that) is generated by NSers and that's the awesome stuff I come to NSG for, not stuff thats plastered all over the internet elsewhere.
