This sounded much more impressive until I actually did the math...
42 people in the credits at version 4.5.
So, being liberal, I will assume 100 people on staff, and an average
salary of $60000K US. I'll throw in overhead of 50%. Then I'll add a 50%
profit margin (better than Microsoft!). Now I will assume you make *all*
your revenue from software sales, and that you *only* sell items at a
price point of $245.
100 * $60000 * 1.5 * 1.5 / $245 = 55102
So, assuming you have been churning away at this capacity (and it is
pretty nice, $13.5M per year gross) for seven years, and have never sold
to the same person twice, that would put the total number of users at
385000. Right in the meaty part of the "hundreds of thousands" figure
you are so vociferously disputing.
One would think having "only" hundreds of thousands of users was a bad
thing, the way you talk :)
