The future of reading on the web is easy to change, all we need to do is pay some money for each article we want to read without adverts... Unfortunately, the primary impact of putting up a paywall for premium content seems to be to raise huge arguments about why "information wants to be free", not the reality of what happens without one.
I don't know about most people, but I don't read many articles from the same source: I read a few from some online newspaper, then some from another, then a blog post, etc. Now take NYT.com: the minimum subscription is $15/month - it's absurdly expensive for the three or four articles I might read there. You need to solve micropayments to make paywalls work.
The New York Times paywall seems to be earning them a fair bit of revenue, and they're more than happy to give you the three or four articles a month you'd read there for free-- you're not their target market segment.
