Of course it's not an exact science. It depends also on how many are submitted and how many are using 'that' same advice. But I did get 2 out today at 5 before the hour and they are on the top of page 2 of latest so cant complain too much! My reveal meme got submitted and ended up on page 15 when it came out. Which didn't bother me too much either, because I wasn't too sure I wanted to do it anyways!
But it has to be a imgflip template, so batman slapping robin would feature fast. Just not before noon edt or you will wash up with all the customs that feature at 1 pm edt
