Tumblr’s massive growth in 2011 continues

Looking in the rear view mirror a bit, it’s clear that Tumblr has been on a roll for quite some time now. The service had an amazing 2011 in terms of growth, more than tripling in size over the year (comparing January 2012 with January 2011).

• Tumblr went from 12 to 41 million blogs in 2011 (29 million added).
• Tumblr users created more than 13 billion blog posts in 2011.
• The total number of posts on Tumblr grew by 500%.

And it looks like 2012 might be as strong or even stronger.
As an interesting historical footnote, compare the current numbers with the fledgling years of Tumblr. The numbers back in January 2009, when Tumblr was just under two years old, were:

• 642,000 blogs (which would take 5-6 days to add now).
• A total of 71 million posts (less than 2 days of posts now).
• 185,000 posts per day (about 5 minutes worth of posts today).
