Why unlimited smartphone data plans will probably vanish

In my latest CNN Tech mobile blog post, I riffed on the recent mixed signals Verizon and AT&T have been sending about whether they would offer unlimited data plans for the iPhone. But unlimited data plans may not be around long for any smartphone (or tablet, or mifi device, etc.), simply because of the difficulty of managing a growing proliferation of data-hungry mobile devices on wireless broadband networks.

Ethan Zuckerman: Print Ad Prices Are “Fundamentally Irrational”

Advertising has long been the main source of revenue for mainstream journalism — but have advertisers ever really gotten their money’s worth? On Jan. 16, Ethan Zuckerman of Harvard’s Berkman Institute on Internet and Society examined the economics of print vs. online advertising and posed a very basic — but crucial — question that everyone in the news business probably should consider carefully: Is ad-supported journalism viable in a pay-for-performance age?

Here’s his line of reasoning. I think he makes a very going point….
