I do love the kubuntu community, and spend what some would consider an unreasonable amount on doing certain things twice but there is no philanthropic benefit to having TWO free desktops out there, that won’t help more folks embrace free software neither is there much commercial benefit in having two free desktops.

Great interview with Mark Shuttleworth, spanning a great range of related topics (from Kubuntu to Canonical and business models, not disregarding interesting motivational considerations… “Anyway, what matters to me is that our users are delighted”)
