Excuse me, but are you sure? It was my impression that she often looked up clichés and tropes and assumed they applied universally to this world. At least, some of her notions haven't been right, have they? I can't tell if I'm misremembering.
Aside from general surfing and cliches, she's looked up stats and strats for every enemy she fought, maps of various locations including where treasures, hidden enemies, and glitches are, information about other people she's met, and procedures for accessing areas that would normally only be revealed by going through lengthy quests. She also reads online comments about these things that are written as if the commenters had played the game.
I'll provide some examples specifically from chapters that are still available on this site. She read about how to increase her inventory limit, which lead her to a glitch that let her warp to the golden city from the goddess of light's space. She read about how to deal with all of the enemies in the Terror House dungeon. She read about how the goddess of darkness's voice hadn't been implemented and mentioned that she was popular among the players. She read about the mechanics for the event that is going on in Dwango.
