I'll be brutally honest, he's obviously never read past the first five chapters of the first book. The lols dry up after the first five and generally the book becomes a slog to get through because of the terrible and bland description. There are a few to be had for certain but to become obsessed with it's shittiness makes you significantly more autistic than most. Even I,despite my strange obsession for this series, have breaks and certainly don't have the time to ween my way into Tesch's facebook group to leave ironic comments.
In answer to the last sentence, he thinks he's hilarious. No one else does though.
