2. Open source is a development methodology; free software is a
social movement.
When we call software “free,” we mean that it respects the users'
essential freedoms: the freedom to run it, to study and change it,
and to redistribute copies with or without changes.

One the interesting aspects of the open source world,
particularly for us, is how it's proving to be a fascinating
research community. Open source projects come in many
guises, but a fair number of them are taking an idea and
programming around it to see where it goes and whether it has
value. That's a notion that sounds strange if you believe that
design and programming are separated, but makes a lot of
sense if you accept that they are tied together.
