The difference between 2010 and 2011 is less pronounced, certainly. But if you draw a line across the graph at 1000 distributions per month, then you'll see that most of 2010 is just below the line, but most of 2011 is just above.

Based on the Jan-Nov periods, as it's too early to count December, 2010 had 10883 releases and 2011 had 11131. A small increase, but nevertheless an increase.
