I for one will be happy to pay for in-depth, impartial analysis that takes complex matters and explains them to me simply.
There are enough people out there interested in different things, there's a market there, somewhere. Regardless of that I'm sure most people are sick and tired of tabloids, newspapers with a political agendas and media moguls pushing their views.
I'll pay if you empower me with no BS knowledge and thus a real chance of understanding. Ask me, the potential buyer what I care about, what I'd like to know about and what I do not care for.
Information should be free, instead of asking how you can charge for information maybe you should consider how to monetize transferring free information? wait a moment that's call an ISP. Tax the ISP? -do you see where this is going?
So far we've all been reading what we like for free on the internet, what will your pay service do better? can you demonstrate you're giving me, the reader better value over "free!"? -if you cannot answer that question you should not bother with a pay wall. If you tax at the ISP level and they transfer costs to the customers then customer will move.
So really, what information is not easily accessible to the masses, without passes and logins? high quality research, specialist and niche information. Essentially the sort that has a very low readership and cannot fund itself on ad revenues. Someone will pay for that.
