New criteria for ranking

The exchange page seems to have new criteria for ranking by points and lingQs. What are they?

@josemaria92000 - Nothing has changed here, but do note that the rankings are affected by the filters you have selected at the top left of the Exchange page.

Keep in mind that with our latest update yesterday the exchange page now defaults to show you rankings for the language that you are currently in. You can change the language filter to all to see rankings across all languages but right now initially you will just see rankings for your current language.

Mark, how does one find the monthly summary of the rankings that I sometimes see?

On the Exchange page in the sidebar.
