How to find out "The most popular repositories" on Github?

Once upon a time, we can watch the most popular repositories (Most forked or Most watched) at this page (https://github.com/popular/watched) of Github. like this:

But now when you try to explore repos, you can only see the Top 25 trending repositories. like this: https://github.com/trending

Why Github change this, and is there any way to find out the list of the most popular repos?

Ranking by stars or forks is not working. Each promoted or created by a famous company repository is popular at the beginning. Also it is possible to have a number of them which are in trend right now (publications, marketing, events). It doesn't mean that those repositories are useful/popular.

The gitmostwanted.com project (repo at github) analyses GH Archive data in order to highlight the most interesting repositories and exclude others. Just compare the results with mentioned resources.
