There are a lot of talented, professional people working for free: Linux programmers, Debian developers, Gnome developers....
And don't say they get paid lots of money for it: they certainly didn't get any money when they started.
Are you saying there is less free talent available in the AV arts than in programming?
No I'm not, and I didn't say they wouldn't be successful. They may well be, and I hope they are. The question posed was whether this was the future of TV. I can't see it, there just isn't enough security in it for all those people working in TV to bet their working lives on.
I think there's certainly room for projects like these, and I hope to see more of it. But it's not going to replace regular TV making, much as we may wish it to be so.
