A very interesting post.

However, the "coke" example is a very bad one. We all know that both (the product from Coca-Cola and Cocaïne) are bad for us, whether for the mind or for health. 😁

Regarding considering used-chosen tags on posts as useful information for domains, that's a step I probably wouldn't take. There are so many users who choose inappropriate tags, especially in order to get upvotes. Tags should first of all be compared to the content of the post whenever possible.

That said, this post allows me to glimpse the system you want to put in place and its huge potential to provide services for our platform. Now, I feel very excited and eager to read your next posts.
