I'm the new Product Manager for the Discovery Portal team and I'm happy to be here with all the cool kids! :)
I'm also very happy to announce that we launched a new A/B test on the Wikipedia portal (www.wikipedia.org) as of last night. This test aims to identify whether the use of a more prominent search box, and/or the use of a more informative set of search results (featuring small images and descriptive labels of each result) increases the rate at which users click through from the portal to our projects.
This test will be seen by a small sample (0.05%) of Wikipedia portal visitors. It is due to run for a week, ending on 20 January and we hope to have the results of our analysis soon after.
If you have any questions about the test or about what the portal team is working on and/or planning next, please let me know.
