[Question] Any systems to rate more abstract things?

We have many in place to give us aggregated reviews on books (example: goodreads), films (imdb), restaurants (yelp), places (tripadvisor), apps, etc… Yet it seems like there’s no such thing for abstract yet important stuffs like theories (e.g. Maslow hierarchy), techniques (CFAR’s various), methods...

Without proper research on the issue, I’m still going forth and saying that it’s actually in pretty high need. Do you agree? If not, why? If yes, what does the system look like in your mind, in detail? And more important, how many of us here are willing to roll up their sleeves and together build such thing?
