My view of profit is as follows:

1. The net gain from an activity. 2. For a firm: revenue minus cost.

My position is that people would not use SAGE unless they were gaining
something from it. :-)


The reason I chose the term "market" is because I think SAGE has
evolved to the point where marketing it has become a top priority.
Just to be clear, here is the definition of marketing that I am using:

"Marketing is the process or act of making products appeal to a
certain demographic, or to a consumer."

This is how I view SAGE's potential target audience:

If the goal is to grow SAGE's user base as large as possible, it is my
option that SAGE should be marketed as a lower-cost, massively more
powerful replacement for the scientific calculator.  I also think that
the largest group of scientific calculator users in the world consists
of high school students.

As a number of people have noted on the SAGE lists, getting current
mathematicians to learn SAGE is extremely difficult.  I think that for
every mathematician that one can get to use SAGE, the same amount of
effort would be able to get 10+ high school students or other
scientific calculator users to use it.  Over time, this would
translate into a large and increasing number of young mathematicians
using SAGE.  I think that a large user base would also solve SAGE's
programmer shortage problem because programmers could be recruited
from this group fairly easily.

Is there anyone interested in starting a SAGE-based company and
offering SAGE as a web service to the scientific calculator target
audience?  If so, I think that the university I work for could be your
first customer.  I also have some ideas on how to make a SAGE-based
company thrive.
