Englightenment is Magic

 I'm not making the content I want to, but still consuming! So I have to share this fic, Harry Potter and the Methods of Rationality - a fic where Harry is OOC af but it works well within the 'verse, and between magic and applying Muggle science to situations, plenty of hijinks ensue at Hogwarts. (Ron isn't much present in it, disappointingly, but I do like the author's take on Hermione, Draco, McGonagall and Quirrell.)

But I've linked above to the chapter where the author writes a segment of fic where Rationality is applied in that 'verse for a bunch of fandoms, including Lord of the Rings, Naruto, the Matrix, My Little Pony, Twilight and Hamlet. Go have a read, it's fun
