How about this for a paywall twist.... a US newspaper publisher has decided to charge users a fee for posting comments on its newspaper website.
From tomorrow, the Sun Chronicle, a Massachusetts paper, will charge would-be commenters a nominal one-off fee of 99 cents. But it has to be paid by credit card, which means providing a real name and address.
And the name on the credit card will be the name that will appear on comments. So it's goodbye to anonymity.
I don't think they'll be getting many comments...
