According to Media Culpa a blog that apparently obsessively tracks these things, photo-sharing site Flickr has hit the 5 billionth photo milestone today with the above, uploaded  by Flickr user yeoaaron. Media culpa blogger Hans Kullin also points out that Flickr has been growing at about 1 billion photos per year, over the past 3 years, eclipsed in market share by social giant Facebook which hit 15 billion photos uploaded in April of 2009. As Facebook claims it was uploading over 2.5 billion photos a month in February of 2010, we’re loosely guestimating there are somewhere between 30 and 50 million photo uploads on the site currently. I’ve contacted both Flickr and Facebook for more info and will update as soon as they respond. In the meantime sit back and enjoy Aaron Yeo’s artistic interpretation of the view of the Woodward’s Building in Vancouver.
