Not too surprising (well, it's always easy to be smart after you know the figures :-)).

But the basic underlying service hasn't changed that much since I started (in early 2007). It's still laggish, it still crashes, you still need to figure out your own purpose for being there, it still requires a semi high end PC and a lot of free personal time.

I think one out of 10 is pretty good actually, in software (shareware) the rule of thumb is one out of 100.
