There are some good comments on the Itai News site:
"Genius"
"For me, the final 'ooo' perfectly captures the sense of isolation the poet talks about"
"He must be the kid of some yakuza boss"
"I am a NEET. Ooo ooo ooo ooo ooo."
"Rock n' Roll!"
"I'll bet his teacher was pissed off"
"First keitai novels and now this. Japanese culture is going to ruin"
"What do you reckon the other entrants felt when they saw what they had lost to?"
"Actually, if you say it out loud, it does sound good."
"Are kids going to be studying this poem in the future?"
