I'd like to subscribe to The Economist, but a 12-month digital-only subscription costs US$285 from Australia, nearly double the US figure, which I can't yet justify as a relatively casual reader.
The leaky paywall (and convenient scraped ePub versions for eReaders) makes it even easier to not contribute to funding quality journalism. If I could choose a dollar amount, I'd happily donate US$75/year recurring for what I'm currently paying $0/year for.
