Our memes are just so awesome it takes them that long to recover from the sheer brilliance. Lol lately for me at least the ones that have taken the longest make it to front page.
I have noticed that!
Most views ones ever had that I posted is 60,000 and it took 10 hours to be featured lol.
It certainly seems more to do with the rate you acquire upvotes, then the length of time it’s up, comes second or third.
