I agree with your comments (in the comment above) about the Guardian but it’s not yet totally clear whether their approach is sustainable in the long term is it?
Their (now commercially available) Open Platform is also interesting, but again, not yet clear whether it will actually make money?
I’m embarrassed to admit that these days (apart from an occasional Saturday or Sunday paper) I only read one paper newspaper – the free Metro that I pick up when I walk into the office every morning. And I only read that to pass 20 minutes at lunchtime 🙁
