“[Richard Dawkins, the evolutionary theorist, who coined the term meme] pointed out that a meme was like a living organism, surviving not in the real world, but in our world of ideas.
Like a real organism, memes could live and die, and more importantly, they could evolve. Every time a meme is passed from person to person, it gets touched, changed, and—sometimes—improved.
Once a meme has been passed around enough, it ceases to evolve as quickly and just becomes a building block for future memes.” 
Just like your favorite memes, successful products and ideas are building blocks for future products and ideas. Everything we have is built on top of previous ideas, memes.
When building, you’re also enabling what comes next.
If you can, make it as easy as possible for the next iteration of ideas to happen.
