Something Awful user "Grei Skuring" claimed that he is the first one who had ignited the "content aware scaling" trend on the internet.
He has given these links to prove his claim
Something awful forum archive(it requires an update to view the content so i can't say anything about it)
Photoshop phriday archive on SA
(Archive relase date is Mar 02, 2012. It gives the credit to the Grei. it is possible that this have been spreaded through the Tumblr from here)
Other archive on SA(Archive relase date is Mar 09, 2012.)
It makes more sense to give the credit to him and SA more than chickensnack and tumblr for me. But i am not really sure.. I want to see the thread archive first, so i have replied him to screencap those archives for me and now i am waiting for it. What do you think? Does he deserve the credit?
