K-On! was surprisingly good and typically I don't like moe anime. It was part ridiculous and part actually entertaining. I always imagine that as they made the series they were thinking
"Okay, so what kind of girls do otaku like?"

"Well you know, loli, rich young polite girls, sometimes silly ones, tsundere, and most of all cute"

"OKAY BLACK HAIRED TSUNDERE GIRL WHO IS SCARED OF THINGS BUT SORT OF ACTS COOL AND TOUGH, RICH GIRL WHO IS NICE AND SOMEWHAT QUIET, LOUD OBNOXIOUS GIRL JUST IN CASE AND A STUPID GIRL WHO IS CUTE IN A DUMB WAY. NOW JUST THROW IN THREE SCENES OF THE BLACK HAIRED GIRL HAVING SOMETHING EMBARRASSING HAPPENING TO HER AND WE'VE GOT OURSELVES A SHOW."

Then halfway through they were browsing 2channel:
"SIR IT APPEARS THAT WOTAKU LIKE SMALL REALLY TSUNDERE LOLI-TYPE GIRLS"

"SHIT, WE DON'T HAVE ANY OF THOSE, PEOPLE LIKE MIO SO LETS MAKE A TINY MIO THAT'S REALLY REALLY TSUNDERE AND LOLI."

All the while hundreds of NEETs are watching saying "Marvelous"
