BBC says that the Times's paywall is working...at keeping readers out:

More than 100,000 people have paid to go behind the Times and Sunday Times' new online paywalls but visits to their websites have fallen by about 87%.

Times Online was registering about 21 million unique users a month to its front page earlier this year but the figure fell to 2.7 million last month.

Which means that The Guardian's estimates back in July were just about right. Which also means that The New York Times should probably still reconsider their plan to build a paywall in January.
