The same thing happens in the politics stream. I can't even guess how many really good memes I've made that sit in queue for 12 hours, and when they finally get accepted - they show up on page 3 sorted by newest.....nobody ever sees them.
Here’s an alternative fun stream that I’ve taken to submitting to every time I come up with a “fun”-style meme. Not nearly as active, so it moves at a slower pace and your content will at least be seen and probably upvoted by someone. imgflip.com/m/the_new_imgflip
There are other similar-to-fun streams that are a bit more established like Memes_Overload.
