Just to clarify, the mission statement of the Sage project is:

   "be a viable alternative to Maple, Mathematica, Magma, and Matlab (ASAP)".

Since those systems (except Magma) all *do* have over a million users, and
all of those systems costs > $1000, I think it is highly unlikely that we can
genuinely say that we have really achieved the above goal if Sage doesn't also
have a million users.

To reiterate, the goal is certainly *not* to have a million users.
It's the goal
listed above.  One measure of whether Sage has truly succeeded at
that extremely difficult goal is the number of users.     I'm not
screwing around;
I really want to achieve the goal in quotes above -- the issue is just that it
is quite vague, so it is useful to have some concrete measures of what it
means.

Sage is not just aimed at research mathematicians.

Huh?  Why???  That just doesn't make any sense.

Your goal is to create a viable open source alternative to Magma, and if
that were achieved you would have succeeded.   That's a reasonable goal,
but it's not the goal of the Sage project, which is to be a viable alternative
to Maple, Magma, Matlab, and Mathematica.

Your goal is not the same the as the goal of the Sage project; it's
only 1/4th of the goal.

Indeed -- ivory tower :-).
For a number of different reasons, the more modest goal of just
being a viable alternative to Magma is actually harder long term than
the goal of being a viable alternative to all four systems.   I would have to
write a lot to explain this, and I can't write now since I just got up and
I'm hungry.  Anyway, here's a quick analogy though.
Imagine if Firefox were an extremely good web browser but it *only* worked
for browsing web sites about mathematics.  I probably wouldn't use
it, and I seriously doubt Google would be giving Mozilla $50million
(or whatever)
a  year to develop it.

There is an old quote here from Dec 2005 in which
Richard Fateman declares Sage "essentially doomed":

   http://sagemath.org/misc/fateman_on_sage.txt

It suddenly seems kind of relevant.
