I’ve created a page that lists the top 100 articles on MDN, based on traffic. This may be useful to localizers, if you want to be sure that you’re covering topics that are interesting to MDN visitors. I intend to update this list roughly once a month, and in the future, I’ll flag items that are new to the list.
If this is helpful to you, please let me know. I’m also interested in hearing how the list could be made more useful (for example, a macro that tracks the percentage of completion of this list for a given locale).
