Since I have been rewatching the content vs structure episode it occured to me to post this here in case no one hasn't yet.
I've first been introduced to TvTropes some 2 years ago or so and it has shocked me from the structural standpoint.
It's basically a site which names common tropes across any media and real life (anime and manga, live action tv, comics, literature, real life, mythology...).
It even has tropes named "TvTropes will ruin your life" and "TvTropes will enhance your life" as a meta joke and as another resource to read and learn.
I have no idea whether it will actually improve your life or worsen it but the usual effect is that you can tell how common stories will end (sort of a limited prophetic ability).
And of course they have many, many tropes for their own website and many others.
