This is what subscriber links are for - when a LWN article is
relevant to a specific discussion, a subscriber can use their
discretion to post world readable link to the pay-walled article so
everyone is able to read the article....

This is one of the reasons I really like LWN and the way Jon has set
up subscriptions (and encourage anyone who doesn't subscribe to do
so). The paywall is something I *choose* to participate
in to get articles as quickly as possible, but have the option of
being able to let non-subscribers read articles immediately if *I*
consider it relevant to a discussion. That's definitely the case
here....

That said, a link has aleady been posted, so I don't have to do
anything but cheerlead here. :)

Cheers,

Dave.
