We are asking because we're just curious how many users sites have. Someone
was asked me how many users the biggest sites had, so I just wanted to ask
to find out. I believe the person was asking me to find out where we are in
order to gauge how much work it'll be to support more users going forward.

As a note on establishing limits in the code - our goal is to remove limits
from the code. A big part of moving to C++ is the desire to more readily
support resizing containers and data structures, and I hope people see that
we're trying to remove static limits on quantities in our code.
