I agree we need real user input to help guide the design, just so long as we
don't let ourselves be completely constrained by what the initial small user
base wants/likes (the way Unix make did when it had 10 users).  I think if we
warn alpha/beta users that public interfaces are subject to change, we may be
OK.
