I think it's a generational thing. Older folks, like, oh, say, Rupert Murdoch, believe that a newspaper is a newspaper, no matter what its format, and you should pony up for it. Serious investigative journalism costs real money, they say. Fair enough. But of course, Murdoch goes too far, in pricing content too high and with this nonsense of trying shake down search engines for even linking to content.
Middle-age folks like me, who grew up w/o the internet but are still young enough to fully embrace it, might be willing to pay, but as yog said, watch that price. We know that distribution costs on the web are close to nothing, so don't price your content as if it costs the same as print. I don't know what that price is, but you better keep it down and offer a la carte pricing too.
The younger generation, the people who grew up with the internet, well, most of them figure you're a chump if you pay for *any* internet content, so who knows how you get them to suddenly value it. But media companies only have themselves to blame for not creating pay models years ago that could have steered cultural attitudes about the dollar worth of journalism on the web.
