From @wikicommons, RT by @wikipedia and @wikimedia:
Check out the results from the ninth #PictureOfTheYear contest! View them at http://commons.wikimedia.org/wiki/Commons:Picture_of_the_Year/2014/Results
(taken from the suggested tweet text in the share link on the linked page)
Perhaps someone else has time to write up a FB/G+ text. Not sure about the POTY team's announcement plans, but this is already running in a site notice on Commons. Would make a great blog post of course as in previous years (https://blog.wikimedia.org/c/communications/picture-of-the-year-communicatio... ).
