Why "Flappy Bird" so popular?

[Lightningxdash02]

it's this game on your phone app or around facebook.. in which whether device you used. Everyone talks about it on school. Mention that game every single day, plus try playing it during class time, telling which level you are and yeah you get the whole thing. I tried checking that game. But they're some problems on my computer.. so I can't necessary play it. But do any of you people know why it's popular, or give more information about it liked how it started and what makes people liked it? It's not liked if your friend likes it, means you should liked it too. Our that because it's popular that everyone plays it doesn't means you should play. Not to mention, see it everywhere on facebook.
