Aside from the cool-looking characters, there's something about this one that just resonates well. If I have to explain it then the part where the characters explain to each other that they're smart was the best. It was rather, well, smart. And certainly not something many manga does.
Shonen manga - Naruto, Luffy, and other shonen idiots
Shoujo manga - stupid female protagonist whose one good point is her "honesty" or "innocence" or "hardworking"
Seinen/Josei manga - adults and their boring issues, and even the most glamorous life is mundane
Bakuman - we're smarter than you and we're going to make it big, get over it.
Sure, the characters might be wrong about their own intelligence (many teenagers do have an inflated sense of their own sophistication, the poster included), but the attitude was impeccable.
I'm on.
