The other day, when I was extolling the merits of Scheme for agile

I'm thinking it might be helpful to have a counter on the plt-scheme
home page of estimated number of students who've been through HtDP.
Like number of Big Macs served, or the US national debt, only
desirable.
The number of Scheme programmers may be smaller, but Scheme
programmers have passion, and passion is what moves the ball forward.
On the other hand, I've worked in <foo>-only houses (foo is C++ or
Java or whatever), where management would respond that what moves the
ball forward is not passion, but planning, management, project
tracking, Sigma-6, ...
There is a tension between freedom (expressiveness) and management.
In successful projects, sometimes programmers have the bright ideas
and impress or even hire management, and sometimes managers have the
bright ideas and hire programmers.
HtDP brings discipline to the wild and crazy coders without tying
their hands. They learn they win in the end by developing the habit
of thinking first.
PLT has done incredible work to make a platform that is well-
engineered and flexible enough for multiple development styles in the
spectrum of development cultures. In time, there will be more great
applications coded in Scheme that will attract attention, especially
as the world moves to multicore architectures.
A count of HtDP graduates is a great idea, but the market will also
want to know where to find them.
