Any link list, or domain list is not worth much without any rating, or meta. I lead a hobby project, and I am not expert, so I provide ratings based on what kind of data pages provide (title, social, description), and my own manual voting system. It is not ideal, but it is something. Also I provide tags, so it is easily known what the domain provides, or domains can be filtered by tags.
I know that you cannot count and visit every domain, so the list will never be finished, but I am happy with the results.
