One of the best things about memes is their ability to surprise. While it's true that the same old ideas and formats get recycled again and again for years on end, this is part of what prompts the creativity that they are famed for. We only need to look at a massive meme like Kevin James to see how the meme making collective can take a limited premise and turn it into something varied and endlessly entertaining.
The downside of this is that we have to dig through a lot of dirt to find the jewels, metaphorically speaking. No matter how curated and condensed a big ol' pile of memes are, that's always going to be the case. That's what keeps the levels of entertainment high, and expectations low. It's the ideal mixture, and we're going to keep on capitalizing on it for as long as it will let us.
