Before starting this blog, I would like to explicitly acknowledge Clay Shirky's excellent article on what he calls "Situated Software".

To quote, "This is software designed in and for a particular social situation or context", rather than what one could call mass-market software. I'd like to acknowledge it because it is very astute, and because his thinking has definitely influenced ours. (The term "Situational Software" emerged independently, as far as I know, and describes something slightly different.)
