Hello,
The Discovery Team recently added descriptive text to the Wikipedia.org page footer in order to give visitors a better idea of what the sister wiki projects are really all about. Check it out at www.wikipedia.org or view a mobile screen capture here https://www.mediawiki.org/wiki/File:Descriptive-text_sister_projects-wikipedia_footer_mobile.png .
We also wrapped up a quick, one question survey that ran for a week on the portal to determine how visitors arrive at the page. The results showed that many of the visitors arrive by clicking on a bookmarked link or by typing in 'wikipedia' in their browser. We had many encouraging and uplifting comments as well - see the full results here https://commons.wikimedia.org/wiki/File:Wikipedia_Portal_Survey_-_May_2016.pdf .
In the coming weeks and months we'll be reaching out to many of those survey takers who graciously provided their name and email addresses to engage in deeper conversations on how they use the portal and Wikipedia in general.
As always, more detailed information is available on wiki for the Wikipedia Portal https://www.mediawiki.org/wiki/Wikipedia.org_Portal and A/B testing https://www.mediawiki.org/wiki/Wikipedia.org_Portal_A/B_testing.
On behalf of our happy little Wikipedia.org Portal team,
Deb -- Deb Tankersley Product Manager, Discovery Wikimedia Foundation
