I started visiting 9GAG few month back.From then I spend more time of 9GAG than fb.
As 9GAG is user generated community website. You can see each and every type of entertainment over there.Main focus of 9GAG is entertainment(humor) rather than personal sharing. So no such idiotic personal pics on 9GAG. Even you could find NSFW can section where you could fine adult(non-nude)pics. As 9GAG is community base even you can upload pics, gifs, videos and meme and start interacting with other users.
