The BBC calls it Rise of the anoraks (“anoraks” being English slang for people who wear uncool windbreakers and study science or math). Demos, probably the UK's most interesting think tank, calls it The Pro-Am Revolution: How enthusiasts are changing our economy and society.
Demos says that the people it calls “Pro-Ams”—meaning “amateurs who pursue a hobby to a professional standard” including serious amateur astronomers and open source coders—should receive government funding to “promote community cohesion”.
It's nice to see the bottom-up revolution being noticed. Whether it needs subsidizing, though, and how one would do so without distorting it (and without enormous waste), seem like fairly hard questions. But I haven't yet read the full report.
