On the difficult economics of online video. (thanks, montoya)
I think this applies to almost all web content - video just takes a lot more effort, equipment, and bandwidth to produce and serve than text, and is therefore harder to be profitable with. (Video also has a much smaller audience on the internet than text.)
With ad response rates so low and advertisers so cheap and terrible, I have severe doubts that there’s much of a future in the for-profit online content business except for the people at the very top. For everyone else, online publishing might just require other motives.
