Flickr hits 400 million photos

Last Friday, 23rd Feb 2007, the Flickr uploaded photo counter hit 400 million with this otherwise unremarkable photo.

I previously looked at the growth of Flickr uploads by plotting uploads by Caterina Fake, to get a time series.  I've since found how to get a specific numbered photo by use of the Flickr API, so can now get dates for exact upload milestones.  The photos for each of the past 7 50 million milestones are:

• 400000000 IMG_5809
• 350000000 jan2007 006
• 300000000 Capsized palm tree on Khao Lak beach, Thailand
• 250000000 IMG_5935-Cefalu alleys
• 200000000 Pará pará!!
• 150000000 2006.05.14.crew (9)
• 100000000 Two beauties

The graph shows a remarkably straight line from 150 million through to 350 million, but that jump to 400 million is ahead of the curve - the rate of uploads has accelerated once again.  (Must be all those new cameras purchased over the holiday period!)
