i'm drawn to FOSS by my values, and David really is out there living his values. we have a number of people in this space who strive for that same ideal -- and i appreciate them all -- but it really is too easy to get bogged down in the low level stuff. David is so important to this space because ironically enough, he escapes the last 'S' in that acronym: he shows us a world in which FOSS can be so much more than "just" software.
