Young minds are more vulnerable to memetic infections. They are programmed to nature to absorb memes less critically - and have had less time to build up a memetic immune system. This is a kind of double vulnerability. So, it is no great surprise to see the nation's youth gripped by meme fever. This is mostly a recent phenomenon, though. Major news outlets have coverage:
Time has: "College Humor: School-Themed Memes Are Taking Off".
Huffington Post has an article documenting the spread of internet memes via college and university campusses - and their online sharing facilities.
The Daily Collegian has: "Memes unite the masses".
Mashable has: "20 Colleges Where Internet Memes Are All the Rage".
MediaShift has: "College Memes Madness: Students Posting Non-Stop on Facebook".
USAToday has: "Campus-themed Internet memes go viral".
