Did you know that about 3000% of internet statistics are made up on the spot? :)
But seriously, I don't know if most memes mentioning the front page make it there. I mean, we definitely see some of them make it, but we probably don't see all the ones that don't, if you know what I mean. Imgflip has a lot of memes about upvotes, front page, submissions not featured, other users, etc etc etc
