"Yesterday we had an open source event in BT's auditorium called "Open source - open for business". If you'll excuse the rather corporate-sounding title, it was actually a really cool day. There were elements of preaching to the converted - a large proportion of the audience were already open source advocates - but I'm sure those who were new to the subject would've left the event inspired by how compelling the argument in favour of open source has become."
