Check out this cool graph (produced by David Miller) showing how the Zooniverse has evolved and expanded since the launch of Galaxy Zoo in 2007. David made this plot last year when we had 740,000 subscribed users. Since then we have added 5 new projects (namely Planet Four, Notes from Nature, Space Warps, Worm Watch Lab and Plankton Portal) and our citizen scientist user-base has grown to over 887,000! Even more projects are on the way and we believe that the Zooniverse will continue to expand at an accelerating rate.
