Hello,
The Discovery team recently updated the wikipedia.org portal page to detect what the visitor's browser's preferred language(s) are and then arrange the language links around the globe to match those language preferences.
Earlier this year, we ran a successful A/B test https://www.mediawiki.org/wiki/Wikipedia.org_Portal_A/B_testing#A.2FB_test:_browser_language_detection_.28completed.29 that proved promoting our visitor's preferred languages resulted in increased visibility and interest into these projects. Also, the display of '*The Free Encyclopedia*' phrase is now localized to the visitor's first preferred browser language. If there isn't a translation available, the phrase will be displayed in English (view a screenshot https://commons.wikimedia.org/wiki/File%3AWikipedia_portal_top_10_links_re-sort.png) as it currently is today.
Additionally, a new A/B test https://www.mediawiki.org/wiki/Wikipedia.org_Portal_A/B_testing#A.2FB_test:_languages_by_article_count_.28in_progress.29 will kick off this week to determine if the listing of languages by article count can be displayed in a more modern and streamlined way without decreasing usage of the links. Our goal is to promote easy scrolling through the long list of languages by article count, but in a dropdown format while also providing greater discovery of the sister wiki project links.
More information on past and future work can be found on the wiki page https://www.mediawiki.org/wiki/Wikipedia.org_Portal as well as the sprint https://phabricator.wikimedia.org/tag/discovery-portal-sprint/ and backlog https://phabricator.wikimedia.org/tag/discovery-portal-backlog/ boards. We're always interested in receiving constructive feedback from the community: if you have a question or comment, please start a discussion on the talk page https://www.mediawiki.org/wiki/Talk:Wikipedia.org_Portal.
Cheers,
