I'm not sure I like the idea of calling the use of open source tools "slow computing", and connecting it up in people's minds the way we think about a middle-class fashion.

Or maybe I'm just concerned about the middle class hipsters choosing open source tools ironically or without thought. It might give it an air of exclusion it does not - can not - deserve. I don't want open source tools to become equivalent to a mini penny farthing.

But if it makes people sit up and think the way Whole Foods and the organic food movement has, well, maybe it could work.
