Interesting take on the crowd funding issue. I expect to see more of these sorts of creative things. Advertising debt is annoying. And sadly people like PA with their 2 ads get nailed because people have been so massively inundated with ads all day that even one more is painful. Another experiment they haven't tried, but would be good to run, would be to make the site subscriber only with the long tail free. So imagi…
Unfortunately for PA, their content is probably 90% games/pop culture topical. After a month it'd be completely stale and irrelevant (with exceptions of course). I think the better move would be to have pay users not have to see any ads. Simple web re-design to remove that for pay users, otherwise free users still have to look at the ads. There are a ton of sites that do this and are quite successful.
They clearly want to stop spending effort on ads altogether and spend it on new content for their readers, instead.
