Except for the fact that almost every single image posted on tumblr originates from other sites like reddit and 4chan (ie where the rage comics came from that this picture delightfully abuses).
Seriously. Tumblr mostly consists of 15 year old uninformed hipsters who think the website is somehow this entirely original and exclusive club. Why this happens, I do not know.
