MJ Ray points towards a BBC Radio 4 programme on Open Source by Paul Bennun.
I've just listened to the programme and it contains some wonderful ideas about how software is unique in the world, being a collection of ideas rather than a collection of physical components. It's an insightful, well balanced exploration of Free and Open Source software and how it is a social rather than technological phenomenon.
I particularly liked a quote from Nick McGrath, Head of platform strategy for Microsoft in the UK.
“We don't compete with the Open Source community, that would be like trying to compete with the weather”.
