Be careful. So will the less-than-best essays and teachers. It's a form of hindsight bias: you think this thing is obvious, but your thoughts were actually quite inchoate before that. A meme - particularly a parasitic meme - can get itself a privileged position in your head by feeding your biases to make itself look good, e.g. your hindsight bias.

When you see a new idea and you feel your eyes light up, that’s the time to put it in a sandbox - yes, thinking a meme is brilliant is a bias to be cautious of. You need to know how to take the thing that gave you that "click!" feeling and evaluate it thoroughly and mercilessly.

(I'm working on a post or two on the subject area of dangerous memes and what to do about them.)
