There comes a point when you need to get over yourself. Everyone knows that a wheel is round. I'm sure that, at some point, there was an individual who pointed this out for the first time but that didn't mean that no one else could or should point it out again. On the contrary. A meme is often referred to as a mind virus. It's an idea that spreads by virtue of the inherent value it holds to a given individual, inspiring that individual to pass it on. It is good social etiquette to give credit to the originator of that idea if at all possible but in doing so, ultimately it makes you look just as good as the originator you're noting. It's shows you in a light of someone who is well read and practices good manners, something which anyone can appreciate as virtuous.
