Here are the final survey results, based on 18,199 global responses as of July 8, 2014, when all surveys were discontinued:
 * Note that this was an optional survey, so approval rates should not be cited as a conclusive metric, as they are subject to self-selection bias. The primary purpose of the survey was to collect user comments in order to improve the tool -- not to use approval ratings as a definitive measure of success.
 * Keeping this caveat in mind, a majority of global respondents found the tool "useful for viewing images and learning about them" (56% "useful", 35% "not useful", 9% "not sure"), based on total unweighted survey results, as shown on this spreadsheet
 * When weighted to match global Wikipedia readership for each language, fewer respondents found the tool "useful" than "not useful" (39% "useful", 50% "not useful", and 10% "not sure"). See [$spreadsheet this spreadsheet] for raw survey figures, and [$mvtalk discussion page] for details on how the per-language results can be normalized to match global readership, for a different perspective on these approval ratings.
 * Cumulative "useful" approval ratings by language: English 36%, French 70%, Spanish 78%, Dutch 59%, Portuguese 81%, German 30%, Hungarian 63%, Catalan 71%
 * In the month following launch, daily "useful" rates gradually increased on the [$en-trends English] Wikipedia -- and to a lesser degree, on the [$de-trends German] Wikipedia.
 * On the English Wikipedia, we observed a daily "useful" increase from 23% to 47% between the June 4 launch and July 8, as shown in the graph to the right and on [$trends-dash this dashboard]. This is based on 6,415 daily responses ranging from 492 to 71 responses/day.
 * In the last two weeks from June 24 to July 8, more English users found Media Viewer useful for viewing images (50%) than not (39%), based on 1,291 responses for that period, as shown on the graph to the right and on [$sm-dash this dashboard].
 * These findings suggest that users found Media Viewer more useful for viewing images over time, as they became more familiar with the tool, and as new features were developed based on user feedback.
 * We also observed different responses between readers and editors: on average, [$en-readers 62% of English readers found Media Viewer useful for viewing images], while [$en-editors 38% of English editors did not find it useful for viewing images], based on 1,090 responses during the survey's last 2 weeks, from June 24 to July 8, 2014 (see linked dashboards and thumbnails to the right).
 * Focusing on global reader responses, about [$spread 65% of readers found Media Viewer useful for viewing images], based on 7,582 readers responses in 7 languages, over a 12-week period, from 14 April to 7 July, 2014 (see linked spreadsheet and thumbnail to the right).
 * Reader "useful" ratings increased significantly over time for all languages, no matter where they started (e.g.: from 55% to 80% in the first 6 weeks on es, fr, hu, nl and pt).
 * All reader "useful" ratings are above 65% except for German respondents — even English readers end up at 67%, despite an initially negative response.
 * Note that surveys were discontinued once enough user feedback was collected to inform feature development.
 * Most surveys ended on June 29, 2014 -- except for English and German surveys, which ended on July 8, 2014.
