We all thought the New York Times' paywall was a bit harebrained when we first heard about it. But a surprising (and profitable) side effect of it has been an uptick in print subscriptions since it went into effect. It makes sense if you think about it, since you're no longer paying for something you can get for free at your nearest web browser.
Of course, you can still read the online version for free if you're so inclined. [BI via Fishbowl NY]
